TERMINAL FUNCTIONS
TERMINAL
DESCRIPTION
NAME
NO.
VI
2
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 the
GND
3
Inhibit and VO Adjust control inputs.
VO
4
The regulated positive power output with respect to the GND node.
A 1% resistor must be connected between this pin and GND (pin 3) to set the output voltage of the module higher
than 0.6 V. If left open-circuit, the output voltage defaults to this value. The temperature stability of the resistor
should be 100 ppm/°C (or better). The set-point range is from 0.6 V to 5.5 V. For information on output voltage
VOAdjust
5
adjustment see the related application section.
TheVOAdjust pin must never be connected directly to GND. The minimum resistance between VOAdjust and
GND is limited to 240
.
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 drawn by the
Inhibit
1
regulator is significantly reduced. If the Inhibit pin is left open-circuit, the module will produce an output voltage
whenever a valid input source is applied.
