FUNCTION
Low-battery output is an open-drain output that goes low when LBI is less than 1.5V.
Connect to V+ through a pull-up resistor. Leave LBO floating if not used.
Input to the internal low-battery comparator. Tie to GND or V+ if not used.
Feedback input. For fixed-output bootstrapped operation, connect FB to GND. For
adjustable-output bootstrapped operation, connect a resistor divider between V+, FB and
GND. For non-bootstrapped operation, there is no fixed-output option. Connect a resistor
divider network between V OUT , FB and GND. See Bootstrapped/Non-Bootstrapped
Modes section.
Active-high TTL/CMOS logic-level input. In shutdown mode (SHDN = V+), the internal
switch is turned off and the output voltage equals V+ minus a diode drop (due to the DC
path from the input to the output). Tie to GND for normal operation.
1.5V reference output that can source 100μA for external loads. Bypass with 0.1μF
or larger capacitor.
Ground
Drain of the internal N-channel FET. LX has an output resistance of 1 ? and a peak current
limit of 1A.
Power-supply input. In bootstrapped mode, V+ is also the output voltage sense input.
