NCV866752D250R2G Datasheet, PDF (1/20 Pages) ON Semiconductor – 150 mA LDO Regulator with Enable, Reset and Early Warning

NCV8667
150 mA LDO Regulator with
Enable, Reset and Early
Warning
The NCV8667 is 150 mA LDO regulator with integrated enable,
reset and early warning functions dedicated for microprocessor
applications. Its robustness allows NCV8667 to be used in severe
automotive environments. The NCV8667 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 28 mA
(Adjustable Early Warning Thresholds) or 42 mA (Preset Early
Warning Thresholds) 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 down to 1 mA. The
NCV8667 contains protection functions as current limit, thermal
shutdown and reverse output current protection.
