I/O
DESCRIPTION
NAME
NO.
The negative output voltage power node with respect to the GND node. It is also the reference for the
VO
1O
VO Adjust control inputs.
VI
2
I
The positive input voltage power node to the module, which is referenced to common GND.
N/C
3
This pin is active and must be isolated from any electrical connection.
A 1% resistor must be connected between pin 1 and pin 4 to set the output voltage of the module lower
than –3 V. If left open-circuit, the output voltage defaults to –3 V. The temperature stability of the resistor

I
should be 100 ppm/°C (or better). The set-point range is –15 V to –3 V. The standard resistor value for
a number of common output voltages is provided in the application information.
GND
5
I/O
The common ground connection for the VI and VO power connections.
