Ultra Low I
q
150 mA LDO
Regulator with Window
Watchdog, Enable and
Reset
The NCV8768 is 150 mA LDO regulator with integrated window
watchdog and reset functions dedicated for microprocessor
applications. Its robustness allows NCV8768 to be used in severe
automotive environments. Ultra low quiescent current as low as 31 mA
typical makes it suitable for applications permanently connected to
battery requiring ultra low quiescent current with or without load. The
Enable function can be used for further decrease of quiescent current
down to 1 mA.
The NCV8768 contains protection functions as current limit and
thermal shutdown.
