1
Trim: A 1% 0.1 W resistor must be directly connected
3
Remote ON/OFF: Applying a high level signal to this
between this pin and pin 8 (GND) to set the output
input disables the module’s output and turns off the
voltage to a lower value than 3.3 V. The temperature
stability of the resistor should be 100 ppm/°C or better.
The set point range for the 3.3 V model is from 3.3 V to
0.9 V. The resistor required for a given output voltage

When the Remote ON/OFF control is active, the
input current drawn by the regulator is significantly
reduced. If the Remote ON/OFF pin is left open-
