NCV8668 Datasheet, PDF (1/18 Pages) ON Semiconductor – Very Low I 150 mA LDO Regulator with Window Watchdog, Enable and Reset

NCV8668
Very Low I_q 150 mA LDO
Regulator with Window
Watchdog, Enable and
Reset
The NCV8668 is 150 mA LDO regulator with integrated window
watchdog and reset functions dedicated for microprocessor
applications. Its robustness allows NCV8668 to be used in severe
automotive environments. Very low quiescent current as low as 38 mA
typical makes it suitable for applications permanently connected to
battery requiring very low quiescent current with or without load. The
Enable function can be used for further decrease of quiescent current
down to 1 mA.
The NCV8668 contains protection functions as current limit and
thermal shutdown.
