Pin No. Pin Description
1
Trim: A 1% 0.1 W resistor must be directly connected between
this pin and pin 8 (GND) to set the output voltage to a lower value
than 3.3 V. The temperature stability of the resistor should be 100
ppm/°C or better. The set point range for the 3.3 V model is from
3.3 V to 0.9 V. The resistor required for a given output voltage may
be calculated from the following formula.
If left open circuit the output voltage will default to 3.3 V.
The set point range for the 2.6 V model is from 2.6-0.9 V. The
resistor required for a given output voltage may be calculated from
the following formula
If left open circuit the output voltage will default to 2.6 V.
For further information on output voltage adjustment consult the
Application Note 165.

Margin+: When this input is asserted to High, the output voltage
is increased by 5%. This function is independant of trim and
sense.
Pin No. Pin Description
3
Remote ON/OFF: Applying a high level signal to this input
disables the module’s output and turns off the output voltage.
When the Remote ON/OFF control is active, the input current
drawn by the regulator is significantly reduced. If the Remote
ON/OFF pin is left open-circuit, the module will produce an output
whenever a valid input source is applied.
4
Margin-: When this input is asserted high, the output voltage is
decreased by 5% from the nominal. This functions is independant
of trim and sense.
5
V sense +: The sense input allows the regulation circuit to
compensate for voltage drop between the module and the load.
For optimal voltage accuracy Vo Sense should be connected to
Vout node of bypass capacitor. It can also be left disconnected.
6
V sense -: The VSense should be connected to the ground of a
bypass capacitor near the load or left open circuit.
7
+Vout: The regulated positive power output with respect to the
GND node.
8
Ground: This is the common ground connection for the Vin and
Vout power connections. It is also the 0 Vdc reference for the
control inputs.
9
+Vin: The positive input voltage power node to the module,which
is referenced to common GND.
10
Power Good: This pin indicates the status of the output voltage.
Power Good is driven low if output voltage deviates outside of
specified limits.
