Pin Descriptions

Vin:

The positive input voltage power node to the mod-

ule, which is referenced to common GND.

Vout:

The regulated positive power output with respect

to the GND node.

GND:

This is the common ground connection for the

Vin and Vout power connections. It is also the 0 VDC

reference for the control inputs.

Vo Adjust:

A 0.1 W 1 % resistor must be directly connected

between this pin and GND to set the output voltage to

a value higher than 0.8 V. The temperature stability of

the resistor should be 100 ppm/°C (or better). The set-

point range for the output voltage is from 0.8 V to 2.5 V.

The resistor value required for a given output voltage

may be calculated from the following formula. If this

pin is left open circuit, the output voltage will default to

its lowest value. For further information on output volt-

age adjustment consult the related application note.

The specification table gives the preferred resistor values

for a number of standard output voltages.

Inhibit:

The Inhibit pin is an open-collector/drain negative

logic input that is referenced to GND. Applying a low-

level ground signal to this input disables the module’s

output and turns off the output voltage. When the Inhibit

control is active, the input current drawn by the regula-

tor is significantly reduced. If the Inhibit pin is left

open-circuit, the module will produce an output when-

ever a valid input source is applied.

Track:

This is an analog control input that allows the

output voltage to follow another voltage during power-

up and power-down sequences. The pin is active from

0 V up to the nominal set-point voltage. Within this

range the module’s output will follow the voltage at the

Track pin on a volt-for-volt basis. When the control volt-

age is raised above this range, the module regulates at its

nominal output voltage. If unused, this input may be left

unconnected. For further information consult the related

application note.
