FUNCTION
Regulator 1 Input. Supply voltage can range from 2.5V to 5.5V. Bypass with a capacitor to GND (see
Capacitor Selection and Regulator Stability section).
Regulator 2 Input. Supply voltage can range from 2.5V to V IN1 . Bypass with a capacitor to GND (see
Capacitor Selection and Regulator Stability section).
Regulator 2 Output. Sources up to 100mA. Bypass with a 2.2μF ceramic capacitor to GND.
Active-High Enable Input for Regulator 1. A logic low shuts down the first linear regulator. In shutdown,
OUT1 is pulled low through an internal 5k ? resistor. Connect to IN1 for normal operation.
Active-High Enable Input for Regulator 2. A logic low shuts down the second linear regulator. In
shutdown, OUT2 is pulled low through an internal 5k ? resistor. Connect to IN2 for normal operation.
Active-High Enable Input for Regulator 3. A logic low shuts down the third linear regulator. In
shutdown, OUT3 is pulled low through an internal 5k ? resistor. Connect to IN3 for normal operation.
1.25V Voltage Reference Bypass Pin. Connect a 0.01μF ceramic bypass capacitor from BP to GND to
minimize the output noise. Make no other connection to this pin.
Ground. Connect both ground pins together externally, as close to the IC as possible.
Regulator 3 Input. Supply voltage can range from 2.5V to V IN1 . Bypass with a capacitor to GND (see
Capacitor Selection and Regulator Stability section).
Regulator 3 Output. Sources up to 100mA. Bypass with a 2.2μF ceramic capacitor to GND.
Ground. Connect both ground pins together externally, as close to the IC as possible.
Regulator 1 Output. Sources up to 100mA. Bypass with a 2.2μF ceramic capacitor to GND.
Ground. THE EXPOSED PAD AND ALL FOUR CORNER TABS ON THE QFN PACKAGE ARE
INTERNALLY CONNECTED TO GROUND. The exposed pad functions as a heatsink. Solder to a large
pad or to the circuit board ground plane to maximize power dissipation. Do not use as device ground.
