Description
1
SHDN
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.
2
GND
Ground. This pin also functions as a heatsink. Solder to large pads or the circuit board ground plane to
maximize thermal dissipation.
3
IN
Regulator Input. Supply voltage can range from +2.5 V (+2.7 V for V
OUT
= 1.8 V) to +6.0 V. Bypass with
1.0
μ
F to GND (see Capacitor Selection and Regulator Stability).
4
OUT
Regulator Output. Sources up to 120 mA. Bypass with a 1.0
