150 mA LDO Regulator with Enable, Reset and Early Warning

The NCV8667 is 150 mA LDO regulator with integrated reset and early warning functions dedicated for microprocessor applications. Its robustness allows NCV8667 to be used in severe automotive environments. Very low quiescent current as low as 28 μA typical for NCV8667 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 in shutdown mode to 1 μA. The NCV8667 contains protection functions as current limit, thermal shutdown and reverse output current protection.
