Pin Descriptions
VIN: The positive supply voltage input for the module
with respect to the common GND.
VOUT:
This is the regulated output voltage from the mod-
ule with respect to the common GND.
GND:
The common node to which the input, output, and
external control signals are referenced.
Inhibit*:
This is an open-collector (open-drain) negative
logic input that is referenced to GND. Pulling this pin
low disables the module’s output voltage. If Inhibit* is
left open-circuit, the output will be active whenever a
valid input source is applied.
Typical Characteristics
Vo Adjust:
This pin is used to trim the output voltage
over a typical range of ±15 % of nominal. The adjust-
ment method uses an external resistor. The resistor is
connected from Vo Adjust to either the GND or (+)Sense,
in order to adjust the output either up or down, respec-
tively.
Vsense:
An external remote sense input is provided to
allow the regulation circuit to compensate for voltage
drop between the module and the load. For optimal
voltage accuracy Vsense should be connected to VOUT. If
desired, Vsense may also be left open circuit.
