DESCRIPTION

NAME

NO.

2

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

GND

3

4

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

A 1% resistor must be connected between this pin and GND (pin 3) to set the output voltage of the module higher

than 0.6 V. If left open-circuit, the output voltage defaults to this value. The temperature stability of the resistor

should be 100 ppm/°C (or better). The set-point range is from 0.6 V to 5.5 V. For information on output voltage

adjustment see the related application section.

and GND is limited to 240

Ω.

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. When the Inhibit control is active, the input current drawn by the

Inhibit

1

regulator is significantly reduced. If the Inhibit pin is left open-circuit, the module will produce an output voltage

whenever a valid input source is applied.
