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
3
LBO
Open-Drain Low-Battery Comparator Output. Connect
LBO
to OUT
through a 100k
resistor. 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.

REF
1.3V Reference Voltage. Bypass with a 0.1μF capacitor.

SHDN
Shutdown Input. Drive high (>80% of V
OUT
) for operating mode.
Drive low (<20% of V
OUT
) for shutdown mode. Connect to OUT for
normal operation.

BATT
Battery Input and Damping Switch Connection. If damping switch is
unused, leave BATT unconnected.
