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 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 optimum
output voltage accuracy this pin should always be con-
nected 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 that is 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 to a
value within the range of ±10 % 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 up or down, respectively.
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.
