S-19315 Series AUTOMOTIVE, 125C OPERATION, 36 V INPUT, 40 mA VOLTAGE REGULATOR www.ablic.com WITH SENSE-INPUT RESET FUNCTION ABLIC Inc., 2020 Rev.1.1 01 The S-19315 Series, developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator with the reset function, which has high-withstand voltage and low current consumption. Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared for the reset function, so the output is stable even if the SENSE pin falls to 0 V. The output form is Nch open-drain output. 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.
