NCV8668: LDO Regulator, Very Low Iq, 150 mA, with Window Watchdog, Enable and Reset

Product Description
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 µA 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 µA.
The NCV8668 contains protection functions as current limit and thermal shutdown.
