Pin Descriptions
Vin:
T he positive input voltage power node to the mod-
ule, which is referenced to common
GND
.
Vout:
T he regulated positive power output with respect
to the
GND
node.
GND:
T his is the common ground connection for the
Vin
and
Vout
power connections. It is also the 0 VDC
reference for the control inputs.
Inhibit:
T he Inhibit pin is an open-collector/drain negative
logic input that is referenced to
GND
. Applying a low-
level ground signal to this input disables the module’s
output and turns off the output voltage. When the Inhibit
control is active, the input current drawn by the regula-
tor is significantly reduced. If the
Inhibit
pin is left
open-circuit, the module will produce an output when-
ever a valid input source is applied.
Vo Adjust:
A 0.1 W, 1 % tolerance (or better) resistor must
be connected directly between this pin and the output
ground (pin 10) to set the output voltage to the desired
value. T he set point range for the output voltage is from
1.2 V to 5.5 V. T he resistor required for a given output
voltage may be calculated from the following formula. If
left open circuit, the module output will default to its low-
est output voltage value. For further information on output
voltage adjustment consult the related application note.

T he specification table gives the preferred resistor values
for a number of standard output voltages.
Vo Sense:
T he sense input allows the regulation circuit to
compensate for voltage drop between the module and
the load. For optimal voltage accuracy
VoSense
should
be connected to
Vout
. It can also be left disconnected.
Track:
T his is an analog control input that enables the
output voltage to follow an external voltage. T his pin
becomes active typically 20 ms after the input voltage
has been applied, and allows direct control of the output
voltage from 0 V up to the nominal set-point voltage.
W ithin this range the output will follow the voltage at
the
Track
pin on a volt-for-volt basis. W hen the control
voltage is raised above this range, the module regulates
at its set-point voltage. T he feature allows the output
voltage to rise simultaneously with other modules pow-
ered from the same input bus. If unused this input should
be connected to V
in
.
Note: Due tothe under-votage lockout
feature, the output of the module cannot follow its own input
voltage during power up. For more information, consult the
related application note.
Margin Down:
W hen this input is asserted to
GND
, the
output voltage is decreased by 5% from the nominal. T he
input requires an open-collector (open-drain) interface.
It is not T T L compatible. A lower percent change can
be accomodated with a series resistor. For further infor-
mation, consult the related application note.
Margin Up:
W hen this input is asserted to
GND
, the
output voltage is increased by 5%. T he input requires an
open-collector (open-drain) interface. It is not T T L
compatible. T he percent change can be reduced with a
series resistor. For further information, consult the
related application note.
