DESCRIPTION
NAME
NO.
This is the common ground connection for the VI and VO power connections. It is also the 0-Vdc reference
GND
1, 7
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
3
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 of the
module. If left open-circuit, the output voltage is set to its default value. The temperature stability of the
VO Adjust
4
I
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
VO Sense
5
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.
