Description
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.

Description
LDO Input. Input voltage can range from 2.5 to 5.5V. Bypass with 1µF 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

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.
