Pin name

SO-8 pin

PowerSSO-12

Function

SEL3

Output voltage selectors.

Advanced thermal warning output.

If the device detects a junction temperature above the warning

threshold, the pin is pulled low. If an overvoltage condition occurs, a

square wave is provided through the TW output. Leave floating if not

used.

IShort

Programmable short circuit output current input pin. A resistor between

Ishort pin and GND sets the short circuit output current value.

Enable input.

With the Enable high, regulator and reset are operating. With the

Enable low, regulator and reset are shutdown, while the fast discharge

circuit is turned on.

Connect the Enable to Vs to keep the device always enabled

GND

Ground reference.

Reserved to test, connect the pin to Vo.

Reserved to test, connect the pin to GND.

RST

Reset output.

It is pulled down when output voltage goes below Vo_th. Leave floating

if not used.

Voltage regulator output.

Block to ground with a capacitor ≥ 3.3 µF (needed for regulator

stability).

TAB

Connected to ground
