NCV8518B Low Dropout Linear Regulator with Watchdog, Wake Up, RESET, and ENABLE NCV8518B PIN CONNECTIONS SOIC16 EP SOIC8 EP 18 1 16 Wake Up RESET NC Wake Up GND WDI NC RESET GND NC Delay ENABLE NC WDI V V OUT IN Delay NC NC ENABLE NC NC V V OUT IN PIN FUNCTION DESCRIPTION Pin SOIC8 EP SOIC16 EP Symbol Description 4 8 V Regulated output voltage. OUT 5 9 V Input supply voltage. IN 7 13 WDI CMOS compatible Watchdog input. The watchdog function monitors the falling edge of the incoming signal. 2 3 GND Ground connection. 6 11 ENABLE ENABLE control for the IC. Positive logic. If ENABLE control will not be used, connect this pin to V via a 20k current limiting resistor. Internal ESD protection structures will IN clamp the maximum ENABLE voltage to approximately 21 V. 8 15 RESET CMOS compatible output RESET goes low whenever V drops by more than 7.0% OUT from nominal, or during the absence of a correct watchdog signal. 3 5 Delay Buffered reference voltage used to create timing current for RESET and Watchdog threshold frequency from R Delay. 1, 2, 4, 6, 7, NC No Connection. 10, 12, 14 1 16 Wake Up Continuously generated signal that interrupts the microprocessor from sleep mode. EPAD EPAD EPAD Connect to Ground potential or leave unconnected.
