NCV8667
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 mA 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 mA. The NCV8667 contains protection
functions as current limit, thermal shutdown and reverse output
current protection.
Features
