Unregulated IC Supply Voltage Input – Input range from +1.1V to 5.5V. Bypass with a 4.7
μ
F or greater capacitor.
Control pin for output voltage programming. Connect this pin to a resistive divider network between the output
and GND to obtain an output voltage between 2.0V and 5.5V.
Active-Low Shutdown Input – A logic low shuts down the device and reduces the supply current to 0.1
μ
A.
Connect
SHDN
to V
CC
for normal operation.
Inductor Switching Connection – Internally connected to the drain of an N-channel MOSFET.
Output voltage control pin: Connect this pin to the circuit load and cathode of the switching diode.
Common terminal for ground reference.
Low Battery Detect Comparator Input – Connect to a resistive divider network between the V
CC
and GND to set
the Low Battery Detect trip point. The LBI threshold is 0.6V.
Low Battery Detect Comparator Output – Open drain comparator output. This output is pulled low when V
LBI
is
less than 0.6V. LBO is high impedance during shutdown.
