Pin Descriptions
Vin: The positive input voltage power node to the mod-
ule, which is referenced to common GND.
Vout: The regulated positive power output with respect
to the GND node.
GND: This is the common ground connection for the
‘V
in
’ and ‘V
out
’ power connections. It is also the 0 VDC
reference for the ‘Inhibit’ and ‘V
o
Adjust’ control inputs.
Inhibit: The 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 regulator
is significantly reduced. If the Inhibit pin is left open-
circuit, the module will produce an output whenever a
valid input source is applied.
Vo Adjust: A 0.1 W 1 % resistor must be directly connected
between this pin and the GND pin to set the output voltage
to a value higher than 0.9 V. The temperature stability
of the resistor should be 100 ppm/°C (or better). The set
point range for the output voltage is from 0.9 V to 2.5 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 its lowest value. For
further information on output voltage adjustment, consult
the related application note.
