NCV8669 Datasheet, PDF (1/14 Pages) ON Semiconductor – Very Low Iq 150 mA LDO Regulator with Reset and Early Warning

NCV8669
Very Low I_q 150 mA LDO
Regulator with Reset and
Early Warning
The NCV8669 is 150 mA LDO regulator with integrated reset and
early warning functions dedicated for microprocessor applications. Its
robustness allows NCV8669 to be used in severe automotive
environments. The NCV8669 utilizes precise 1 MW internal resistor
divider for Early Warning function which significantly reduces overall
application quiescent current and number of external components.
Very low quiescent current as low as 42 mA typical for NCV8669
makes it suitable for applications permanently connected to battery
requiring very low quiescent current with or without load. The
NCV8669 contains protection functions as current limit and thermal
shutdown.
