FUNCTION
Shutdown Input. When low, the entire circuit is off and V OUT = V IN - V D, where V D is the
forward voltage drop of the external Schottky rectifier.
Selects the output voltage; connect to GND for 5V output, and to OUT for 3.3V output.
Feedback Input for adjustable-output operation. Connect to an external resistor voltage
divider between OUT and GND.
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.
Low-Battery Output. An open-drain N-channel MOSFET sinks current when the voltage at
LBI drops below 1.25V.
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.
N-Channel Power-MOSFET Drain
