NCV8508B:250 mA LDO Linear Voltage Regulator with Watchdog, Wake Up, Reset and Delay Reset
The NCV8508B is a 5.0 V and 3.3 V precision micropower Low Dropout (LDO)voltage regulator with 250 mA output current capability. Microprocessor control logic includes an active RESET (with DELAY), wakeup and watchdog. The NCV8508B Wakeup function brings the microprocessor out of Sleep mode. The microprocessor in turn signals its Wakeup status back to the NCV8508B by issuing a Watchdog signal. The active RESET circuit operates correctly at an output voltage as low as 1.0 V. The RESET function is activated during the power up sequence, during normal operation if the output voltage drops below the regulation limits or if the regulator does not receive a Watchdog signal within a Wakeup period. The Watchdog logic function monitors an input signal (WDI) from the microprocessor. The NCV8508B responds to the falling edge of the Watchdog signal which it expects at least once during each Wakeup period. Its robustness and integrated protection features make it suitable for severe automotive environments.
