Pin Function

Output of LDO1: Requires a minimum 1µF ceramic capacitor-to-AGND.

Output of LDO2: Requires a minimum 1µF ceramic capacitor-to-AGND.

External Input Supply Rail to LDO2 and LDO3. Requires a minimum 1µF ceramic

capacitor to AGND.

Output of LDO3: Connect a minimum 1µF ceramic capacitor to AGND.

Fault Output (open drain).

Switch (Output): Internal power MOSFET output switches.

Switch Ground Pin.

Input Voltage: Requires a close minimum 2.2µF ceramic capacitor to DGND.

Fast-mode 400kHz I²C Data Input/Output pin.

Fast-mode 400kHz I²C Clock Input pin.

Feedback Pin Connected to VOUT to sense output voltage.

Analog Ground. Must be connected externally to DGND.

Enable (Input): Executes default startup sequence. Active High. HIGH = ON,

LOW = OFF. Do not leave floating. The EN pin function is optional if I2C control

is used for startup and shutdown.

External Input Supply Rail to LDO1. Requires a minimum 1µF ceramic capacitor

to AGND.

Exposed Heat-Sink Pad.
