When the output rises above 91% of its nominal voltage, the power-good output is released. When the device is programmed into snooze mode (SNOOZE = LOW), the power-good detector is disabled and PG is high impedance. In normal operation, an external pullup resistor must be connected between PG and OUT, or any other voltage rail in the appropriate range. The pullup resistor should be in the 100-k Ω to 1-MΩ range. If the PG output is not used, it should remain unconnected. absolute maximum ratings over operating free-air temperature range (unless otherwise noted)† Voltage range: IN, OUT, SNOOZE, LBI, LBO, PG to GND −0.3 V to 3.6 V . . . . . . . . . . . . . . . . . . . . . . . . . . . .
