FB
Dual-Mode Feedback Input. Connect to GND for +5.0V output.
Connect to OUT for +3.3V output. Use a resistor network to set the
output voltage from +2.0V to +5.5V.

LBI
Low-Battery Comparator Input. Internally set to trip at +1.30V.
3

LBO
Open-Drain Low-Battery Comparator Output. Output is low when
V
LBI
is <1.3V.
LBO
is high impedance during shutdown.

CLSEL
Current-Limit Select Input. CLSEL = OUT sets the current limit to 1A.
CLSEL = GND sets the current limit to 0.5A.
