NCV8508
5.0 V, 250 mA LDO with
Watchdog and RESET
The NCV8508 is a precision micropower Low Dropout (LDO) voltage
regulator. The part contains many of the required features for powering microprocessors. Its robustness makes it suitable for severe automotive environments. In addition, the NCV8508 is ideal for use in battery operated, microprocessor controlled equipment because of its extremely low quiescent current.
