Description

Active–Low Shutdown Input. A logic low reduces the supply current to 0.1 nA. A logic low also causes

the output voltage to discharge to GND. Connect to IN for normal operation.

Ground. This pin also functions as a heatsink. Solder to large pads or the circuit board ground plane to

maximize thermal dissipation.

Regulator Input. Supply voltage can range from +2.5 V (+2.7 V for VOUT = 1.8 V) to +6.0 V. Bypass with

1.0 µF to GND (see Capacitor Selection and Regulator Stability).

Regulator Output. Sources up to 120 mA. Bypass with a 1.0 µF, t 1.0 Ω typical ESR capacitor to GND.

Connect to GND.
