PIN ASSIGNMENT
PIN FUNCTIONS
PIN
I/O DESCRIPTION
NAME NO.
This is the common ground connection for the V
I
and V
O
power connections. It is also the 0 V
dc
GND 1 I/O
reference for the V
O
Adjust control input.
V
I
2 I The positive input voltage power node to the module, which is referenced to common GND.
A 1% resistor must be connected between this pin and GND (pin 1) to set the output voltage. If left
open-circuit, the output voltage will default to its minimum adjust value. The temperature stability of the
V
O
Adjust 3 I
resistor should be 100 ppm/°C (or better). The set-point range is 5 V to 15 V. The standard resistor
value for a number of common output voltages is provided in the application information.
V
O
4 O The regulated positive power output with respect to the GND node.
