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 ‘Inhibit’ and ‘Vo Adjust’ control inputs.

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 regulator

is significantly reduced. If the Inhibit pin is left open-

circuit, the module will produce an output whenever a

valid input source is applied.

Vo Adjust:

A 0.1 W 1 % resistor must be directly connected

between this pin and the GND pin to set the output voltage

to a value higher than 0.9 V. The temperature stability

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

point range for the output voltage is from 0.9 V to 2.5 V.

The resistor required for a given output voltage may be

calculated from the following formula. If left open circuit,

the output voltage will default to its lowest value. For

further information on output voltage adjustment, consult

the related application note.
