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 1-% resistor must be connected between this
pin and GND (pin 1) to set the output voltage of the
module higher than its lowest value. The temperature
stability of the resistor should be 100 ppm/°C (or better).
The set-point range is 1.2 V to 5.5 V for W-suffix devices,
and 0.8 V to 1.8 V for L-suffix devices. The resistor value
required for a given output voltage may be calculated
using a formula. If left open circuit, the output voltage
will default to its lowest value. For further information
on output voltage adjustment consult the related applica-
tion note.
The specification tables also give the preferred resistor
values for a number of standard output voltages.
