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