Dual mode feedback input. Connect to GND for +5.0 V output. Connect to OUT for +3.3 V
output. Use a resistor network to set the output voltage from +2.0 V to +5.5 V.
Low-battery comparator input. Internally set to trip at +1.30 V ____
Open-drain Low battery comparator output. Output is low when VLBI is <1.3 V. LBO is high
impedance during shutdown.
1.3 V reference voltage. Bypass with 0.1µF capacitor.
Shutdown input. High = operating, Low = shutdown.
Ground
N-channel and P-channel power MOSFET drain.
Power output. OUT provides bootstrap power to the IC.
