NCV8769
Ultra Low Iq 150 mA LDO
Regulator with Reset and
Early Warning
The NCV8769 is 150 mA LDO regulator with integrated reset and
early warning functions dedicated for microprocessor applications. Its
robustness allows NCV8769 to be used in severe automotive
environments. Ultra low quiescent current as low as 25
mA
typical for
NCV8769 makes it suitable for applications permanently connected to
battery requiring ultra low quiescent current with or without load. The
NCV8769 contains protection functions as current limit, thermal
shutdown and reverse output current protection.
