DESCRIPTION
NAME
NO.
This is the common ground connection for the VI and VO power connections. It is also the 0-VDC
GND
1, 7
reference for the Inhibit and VO Adjust control inputs.
VI
2
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

I
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
VO Sense

I
load. For optimum voltage accuracy, VO Sense should be connected to VO. If the sense feature is not
used, this pin may be left disconnected.
VO
6
O
The regulated positive power output with respect to the GND node.
