Overview
NCV8508B LDO Regulator - Watchdog, RESET 5.
0 V, 3.
3 V, 250 mA The NCV8508B 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 NCV8508B is ideal for use in battery operated, microprocessor controlled equipment because of its extremely low quiescent current.
Features • Output Voltage: 5.
