DESCRIPTION

NO.

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

GND

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

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 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.
