Note A:
Characteristic data has been developed from actual products tested at 25°C. This data is considered typical data for the ISR.
Note B:
SOA curves represent operating conditions at which internal components are at or below manufacturer’s maximum rated operating temperatures.

Pin Descriptions
Vin:
The positive supply voltage input for the module
with respect to the common ground (GND).
Vout:
This is the regulated output voltage from the mod-
ule with respect to the common ground (GND).
GND:
The common ground node to which the input,
output, and external control signals are referenced.
Sense(–):
Provides the regulator with the ability to sense
the set-point voltage directly across the load. For opti-
mum output voltage accuracy this pin should always be
connected to GND, even for applications that demand a
relatively light load.
Sense(+):
When used with Sense(–), the regulation circuitry
will compensate for voltage drop between the converter
and the load. The pin may be left open circuit, but con-
necting it to Vout will optimize load regulation.
Inhibit*:
This is an open-collector (open-drain) negative
logic input, referenced to GND. Pulling this pin to
GND disables the module’s output voltage. If Inhibit* is
left open circuit, the output will be active whenever a
valid input source is applied.
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 (-)Sense or (+)Sense,
in order to adjust the output either up or down, respec-
tively. Consult the related application note for the adjust
limits of a specific part.
Margin Dn*:
When this open-collector (open-drain) input
is asserted to GND, the output voltage is automatically
decreased by 5% from the nominal. This feature is used in
applications where the load circuit must be tested for
operation at the extreme values of its supply voltage
tolerance.
Margin Up*:
This is an open-collector (open-drain) input.
When this is asserted to GND, the output voltage is
automatically increased by 5% from the nominal.
