DESCRIPTION
NAME
NO.
This is the common ground connection for the VI and VO power connections. It is also the 0 Vdc
GND
1
I/O
reference 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
3
I
Inhibit control is active, the input current drawn by the regulator is significantly reduced. If the Inhibit pin
is left open-circuit, the module will produce an output whenever a valid input source is applied.
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 defaults to its minimum adjust value. The temperature stability of the
VO Adjust
4
O
resistor should be 100 ppm/
°C (or better). The PTN78000W set-point range is 2.5 V to 12.6 V. The
PTN78000H set-point range is 11.85 V to 22 V. The standard resistor value for a number of common
output voltages is provided in the application information.
VO
5
O
The regulated positive power output with respect to the GND node.
