NCV8508PD50 Datasheet, PDF (1/26 Pages) ON Semiconductor – 5.0 V, 250 mA LDO with Watchdog and RESET

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.
