Pin Descriptions
V
IN
:
The positive supply voltage input for the module
with respect to the common
GND
.
V
OUT
:
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
V
o
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
V
o
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
V
OUT
. If
desired,
Vsense
may also be left open circuit.
