Pin Description

FUNCTION

Regulator 1 Output. Fixed (+1.8V, +2.5V, +3.3V, or +5V) or adjustable (+1.8V to

+11V). OUT1 = 150mA (max). Connect a 10µF (min) capacitor from OUT1 to GND.

Feedback Input for Setting the OUT1 Voltage. Connect SET1 to GND to select the

preset output voltage. Connect to an external resistive divider for adjustable

output operation.

Active-Low, Open-Drain, Power-Fail Comparator Output. PFO asserts low

when PFI is below the internal 1.231V threshold. PFO deasserts when PFI is

above the internal 1.231V threshold.

Watchdog Timeout Period Adjust Input. Connect CSWT to OUT1/OUT for the

internally fixed watchdog timeout period. For adjustable watchdog timeout period,

connect a capacitor from CSWT to GND. Connect CSWT to GND to disable the

watchdog. See the Selecting Watchdog Timeout Period section for more details.

Reset Timeout Period Adjust Input. Connect CSRT to OUT1/OUT for the

internally fixed timeout period. For adjustable timeout, connect a capacitor

from CSRT to GND. See the Reset Output section for more details.

Ground

Active-Low Reset Output. RESET remains low while OUT1/OUT is below the reset

threshold. RESET remains low for the duration of the reset timeout period after the

reset conditions end. RESET is available in push-pull and open-drain options.
