Product Preview
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 operational
requirements for powering microprocessors. Its robustness makes it
suitable for severe automotive environments. In addition to being a
good fit for the automotive environment, the NCV8508 is ideal for use
in battery operated, microprocessor controlled equipment because of
its extremely low quiescent current.
Features Output Voltage: 5.0 V ±3.0% Output Voltage IOUT Up to 250 mA Quiescent Current Independent of Load Micropower Compatible Control Functions: Wakeup Watchdog RESET Low Quiescent Current (100 �A typ) Protection Features: Thermal Shutdown Short Circuit 45 V Operation Internally Fused Leads in SO−16L Package NCV Prefix for Automotive and Other Applications Requiring Site
