S-19514/19515 Series www.ablic.com AUTOMOTIVE, 125°C OPERATION, 36 V INPUT, 250 mA, BUILT-IN WINDOW WATCHDOG TIMER VOLTAGE REGULATOR WITH RESET FUNCTION Rev.1.4_00 © ABLIC Inc., 2019-2021 The S-19514/19515 Series, developed by using high-withstand voltage CMOS technology, is a low dropout positive voltage regulator with the window 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. ABLIC Inc. also offers FIT rate calculated based on actual customer usage conditions in order to support customer functional safety design. Contact our sales representatives for details. Caution This product can be used in vehicle equipment and in-vehicle equipment.
