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

‘Vin’ and ‘Vout’ power connections. It is also the 0 VDC

reference for the ‘Inhibit’ and ‘Vo 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.

Notes:

(i) For operation below 0 °C the external capacitors must have stable characteristics. Use either a low ESR tantalum, Oscon, or ceramic capacitor.

(ii) During soldering of package version do not elevate peak temperature of the module, pins or internal components above the stated maximum.
