DESCRIPTION

NAME

NO.

GND

1, 7

I

The positive input voltage power node to the module, which is referenced to common GND.

The Inhibit pin is an open-collector/drain active-low 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

Inhibit

I

control is active, the input current drawn by the regulator is significantly reduced. If the Inhibit pin is left

open-circuit, the module produces an output whenever a valid input source is applied.

A 1% resistor must be connected between this pin and GND (pin 7) to set the output voltage. If left

open-circuit, the output voltage is set to a default value. The temperature stability of the resistor should be

100 ppm/°C (or better). The standard resistor value for a number of common output voltages is provided

in the application information.

The sense input allows the regulation circuit to compensate for voltage drop between the module and the

used, this pin may be left disconnected.

6

O

The regulated positive power output with respect to the GND node.
