Product Change Notification
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 MΩ 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 µA 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.
