Vin: The positive input voltage power node to the module,which is referenced to common GND.
Vout: The regulated positive power output with respect to theGND node.
GND: This is the common ground connection for the Vinand Vout power connections. It is also the 0 VDC reference forthe control inputs.
Inhibit: The Inhibit pin is an open-collector/drain negative logicinput that is referenced to GND. Applying a low-level groundsignal to this input disables the module’s output and turns offthe output voltage. When the Inhibit control is active, theinput current drawn by the regulator is significantly reduced.If the Inhibit pin is left open-circuit, the module will pro-duce an output whenever a valid input source is applied.
Vo Adjust: A 0.5 %, 0.1 W resistor must be connected be-tween this pin and the GND pin to set the output voltage tothe desired value. The set point range for the output voltage isfrom 0.8 V to 2.5 V. The resistor required for a given outputvoltage may be calculated from the following formula. If leftopen circuit, the module output will default to its lowest outputvoltage value. For further information on the adjustment and/ortrimming of the output voltage, consult the related applicationnote.
Rset = 10 k· 0.8 V
– 2.49 k Vout – 0.8 V
The specification table gives the preferred resistor values for anumber of standard output voltages.
Vo Sense: The sense input allows the regulation circuit to com-pensate for voltage drop between the module and the load.For optimal voltage accuracy Vo Sense should be connected toVout. It can also be left disconnected.
Track: This is an analog control input that enables the outputvoltage to follow an external voltage. This pin becomes activetypically 20 ms after the input voltage has been applied, andallows direct control of the output voltage from 0 V up to thenominal set-point voltage. Within this range the output willfollow the voltage at the Track pin on a volt-for-volt basis.When the control voltage is raised above this range, the moduleregulates at its set-point voltage. The feature allows the out-put voltage to rise simultaneously with other modules poweredfrom the same input bus. If unused, the input may be left un-connected. Note: Due to the under-voltage lockout feature, the output ofthe module cannot follow its own input voltage during power up. For moreinformation, consult the related application note.
Margin Down: When this input is asserted to GND, the outputvoltage is decreased by 5% from the nominal. The input requiresan open-collector (open-drain) interface. It is not TTL compat-ible. A lower percent change can be accomodated with aseries resistor. If unused, this input may be left unconnected.For further information, consult the related application note.
Margin Up: When this input is asserted to GND, the outputvoltage is increased by 5%. The input requires an open-collector(open-drain) interface. It is not TTL compatible. The percentchange can be reduced with a series resistor. If unused, thisinput may be left unconnected. For further information, con-sult the related application note.

The Vo Adjust control (pin 4) sets the output voltage of thePMG 4318 T and PMG 5518 T products. The adjustmentrange of the PMG 4318 T (3.3-V input) is from 0.8 V to2.5 V 1, and the PMG 5518 T (5-V input) from 0.8 V to 3.6 V.The adjustment method requires the addition of a single exter-nal resistor, Rset, that must be connected directly between the VoAdjust and GND pins 2. Table 1-1 gives the preferred value of theexternal resistor for a number of standard voltages, along with theactual output voltage that this resistance value provides.
For other output voltages the value of the required resistor caneither be calculated using the following formula, or simplyselected from the range of values given in Table 1-2. Figure 1-1shows the placement of the required resistor.

$The recommended input capacitor(s) is determined by the470 µF minimum capacitance, and 700 mA rms minimum ripplecurrent rating.
Ripple current and <100 mW equivalent series resistance(ESR) values are the major considerations, along with tem-perature, when designing with different types of capacitors.Tantalum capacitors have a recommended minimum voltagerating of twice 2´ (the maximum DC voltage + AC ripple).This is standard practice for tantalum capacitors to insure reli-ability.
$!The recommended ESR of the capacitors is equal to or less than150 mW. Electrolytic capacitors have marginal ripple perfor-mance at frequencies greater than 400 kHz but excellent lowfrequency transient response. Above the ripple frequency, ce-ramic capacitors are necessary to improve the transientresponse and reduce any high frequency noise componentsapparent during higher current excursions. Preferred low-ESRtype capacitor part numbers are identified in Table 2-1.
6; $Tantalum type capacitors can be used for the output but onlythe AVX TPS, Sprague 593D/594/595 or Kemet T495/T510series. These capacitors are recommended over many other tan-talum types due to their higher rated surge, power dissipation,and ripple current capability. As a caution, the TAJ series byAVX is not recommended. This series has considerably higherESR, reduced power dissipation, and lower ripple current capa-bility. The TAJ series is less reliable than the AVX TPS serieswhen determining power dissipation capability. Tantalum, ceramicor Os-con types are recommended for applications where ambi-ent temperatures fall below 0 °C.
Ceramic capacitors may be substituted for electrolytic typeswith the minimum capacitor value for improved ripple reduc-tion on the input and output bus.
$6.Table 1 identifies the characteristics of capacitors from a num-ber of vendors with acceptable ESR and ripple current (rms)ratings. The number of capacitors required at both the inputand output buses is identified for each capacitor type.
This is not an extensive capacitor list. Capacitors from other vendors areavailable with comparable specifications. Those listed are for guidance. TheRMS ripple current rating and ESR are the critical parameters necessary toinsure both optimum regulator performance and long capacitor life.

The Vo Adjust control (pin 4) is used to set the output volt-age to a value higher than 1.2 V. The adjustment methodrequires the addition of a single external resistor, Rset, that mustbe connected directly between the Vo Adjust and GND pins 1.Table 1-1 gives the preferred value for the external resistor for anumber of standard voltages, along with the actual outputvoltage that this resistance value provides.
For other output voltages the value of the required resistor caneither be calculated using the following formula, or simplyselected from the range of values given in Table 1-2. Figure 1-1shows the placement of the required resistor.

Tantalum type capacitors can be used for the output but onlythe AVX TPS, Sprague 593D/594/595 or Kemet T495/T510series. These capacitors are recommended over many othertantalum types due to their higher rated surge, power dissipa-tion, and ripple current capability. As a caution the TAJ seriesby AVX is not recommended. This series has considerablyhigher ESR, reduced power dissipation, and lower ripple cur-rent capability. The TAJ series is also less reliable than theAVX TPS series when determining power dissipation capabil-ity. Tantalum or Oscon® types are recommended forapplications where ambient temperatures fall below 0°C.
Ceramic capacitors will compliment electrolytic types. Adding10 µF to 47 µF of ceramic capacitance will reduce ripple on theinput and output bus. Output ripple and transient measure-ment accuracy is improved by measuring directly across a 10 µFceramic capacitor.
Table 2-1 identifies the characteristics of capacitors from a numberof vendors with acceptable ESR and ripple current (rms) ratings.The number of capacitors required at both the input and outputbuses is identified for each capacitor type.
This is not an extensive capacitor list. Capacitors from other vendors areavailable with comparable specifications. Those listed are for guidance.The RMS ripple current rating and ESR (at 100 kHz) are criticalparameters necessary to insure both optimum regulator performance andlong-term reliability.
The recommended input capacitance is determined by 800 mArms minimum ripple current rating and 560 µF minimumcapacitance.
Ripple current and <100 mW equivalent series resistance(ESR) values are the major considerations, along with tem-perature, when designing with different types of capacitors.Tantalum capacitors have a recommended minimum voltagerating of 2 ´ (max. DC voltage + AC ripple). This is necessaryto insure reliability for input voltage bus applications. Tanta-lum capacitors are not recommended on the input bus.
The recommended ESR of the output capacitor is less thanor equal to 150 mW. Electrolytic capacitors have marginalripple performance at frequencies greater than 400 kHz butexcellent low frequency transient response. Above the ripplefrequency, ceramic capacitors are necessary to improve thetransient response and reduce any high frequency noise compo-nents apparent during higher current excursions. Preferredlow-ESR capacitor part numbers are identified in Table 2-1.
