DESCRIPTION
NAME
NO.
VI
1
I
The positive input voltage power node to the module, which is referenced to common GND.
This is the common ground connection for the VI and VO power connections. It is also the 0-Vdc reference for
GND
2
the Inhibit and VO Adjust control inputs.
VO
3
O
The regulated positive power output with respect to the GND node.
A 1% resistor must be connected between this pin and GND (pin 1) to set the output voltage of the module
higher than 0.9 V. If left open-circuit, the output voltage defaults to this value. The temperature stability of the
VO Adjust
4
I
resistor should be 100 ppm/
°C (or better). The set-point range is from 0.9 V to 5.5 V. The electrical
specification table gives the standard resistor value for a number of common output voltages. See the
application information for further guidance.
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
Inhibit

I
drawn by the regulator is significantly reduced. If the Inhibit pin is left open-circuit, the module produces an
output voltage whenever a valid input source is applied. Do not place an external pull-up on this pin.
