Low-Battery Output. An open-drain N-channel MOSFET sinks current when the voltage at
LBI drops below 1.25V.
4
4
Low-Battery Input. When the voltage on LBI drops below 1.25V, LBO sinks current.
If not used, connect to V
IN
.
Connect OUT to the regulator output. OUT provides bootstrap power to the IC.
Power Ground. Must be low impedance; solder directly to ground plane.

1.25V Reference Voltage Output. Bypass with 0.22μF to GND (0.1μF if there is no external
reference load). Maximum load capability is 250μA source, 20μA sink.

Feedback Input for adjustable-output operation. Connect to an external resistor voltage
divider between OUT and GND.
