S-19246xxxH Series AUTOMOTIVE, 105C OPERATION, 10 V INPUT, 2000 mA VOLTAGE REGULATOR www.ablic.com WITH SOFT-START FUNCTION ABLIC Inc., 2020 Rev.1.0 00 The S-19246xxxH Series developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator with high-accuracy output voltage and high output current. A built-in overcurrent protection circuit to limit overcurrent of the output transistor and a built-in thermal shutdown circuit to limit heat are included. Also, the S-19246xxxH Series includes the soft-start function to adjust the output voltage rising time at power-on or at the time when the ON / OFF pin is set to ON. ABLIC Inc. offers athermal simulation servic 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.
