S-19504/19505 Series AUTOMOTIVE, 125°C OPERATION,36 V INPUT, 250 mA, BUILT-IN WATCHDOG TIMER VOLTAGE REGULATOR WITH RESET FUNCTION
●The S-19504/19505 Series, developed by using high-withstand voltage CMOS technology, is a low dropout positive voltage regulator with the watchdog timer and the reset function, which has high-withstand voltage. The monitoring time of watchdog timer can be adjusted by an external capacitor. Moreover, a voltage detection circuit which monitors the output voltage is also prepared.
●ABLIC Inc. offers a "thermal simulation service" which supports the thermal design in conditions when our power management ICs are in use by customers. Our thermal simulation service will contribute to reducing the risk in the thermal design at customers' development stage.
