NCV8772 Datasheet, PDF (1/17 Pages) ON Semiconductor – Ultra Low Iq 350 mA LDO Regulator with Enable and Reset

NCV8772
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 mA 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 mA. The NCV8772 contains protection functions as
current limit, thermal shutdown and reverse output current protection.
