DESCRIPTION
NAME
NO.
The common ground connection for the VI and VO power connections. It is also the reference for the VO
GND
1
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 (non-TTL), 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-low, the input current drawn by the regulator is significantly reduced. If the Inhibit pin is left
Inhibit

I
open-circuit, the module produces an output voltage whenever a valid input source is applied. The
PTN04050A Inhibit control circuitry must not be shared with another module. Never connect a resistor
between the Inhibit pin and any other voltage reference or GND.
A 1% resistor must be connected between pin 4 and pin 1 to set the output voltage of the module. If left
open-circuit, the output voltage defaults to –1.79 V, which is beyond the recommended operating range.
VO Adjust

I
The set-point range is –15 V to –3.3 V. The temperature stability of the resistor should be 100 ppm/°C
(or better). The standard resistor value for a number of common output voltages is provided in the
application information.
VO
5
O
The negative output voltage power node with respect to the GND node.
