LDO Input. Supply voltage can range from 2.5 to 5.5V. Bypass with a 1µF
capacitor to GND (see Capacitor Selection and Regulator Stability on page 10).
Ground. This pin also functions as a heat sink. Solder to a large pad or the
circuit-board ground plane to maximize power dissipation.
Active-Low Shutdown Input. A logic low reduces the supply current to < 1µA.
Note: Connect to IN for normal operation.
Reference-Noise Bypass. Bypass with a low-leakage, 0.01µF ceramic
capacitor for reduced noise at the output.
LDO Output. Fixed 1.5, 2.5, 2.7, 3.0, 3.3, and 3.6V output. Sources up to
150mA.

Active-Low Shutdown Input. A logic low reduces the supply current to < 1µA.
Note: Connect to pin IN for normal operation.
Power-OK Output. Active-low, open-drain output indicates an out-of-regulation
condition. Connect a 100kΩ pull-up resistor to pin OUT for logic levels.
Note: Leave this pin unconnected if the power-OK feature is not used.
LDO Output. Fixed 1.5, 2.5, 2.7, 3.0, 3.3, and 3.6V output. Sources up to
150mA.
