Ultra Low I q 350 mA LDO Regulator with Enable and Reset

The NCV8772 is 350 mA LDO regulator with integrated reset functions dedicated for microprocessor applications. Its robustness allows NCV8772 to be used in severe automotive environments. Ultra low quiescent current as low as 24 A typical makes it suitable for applications permanently connected to battery requiring ultra low quiescent current with or without load. This feature is especially critical when modules remain in active mode when ignition is off. The Enable function can be used for further decrease of quiescent current in shutdown mode to 1 A. The NCV8772 contains protection functions as current limit, thermal shutdown and reverse output current protection.
