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.
