S-19222xA Automotive Voltage Regulators ABLIC S-19222xA Automotive Voltage Regulators are developed using high-withstand voltage CMOS process technology. These regulators include a built-in low-on-resistance output transistor, which provides a very small dropout voltage and a large output current. The S-19222xA voltage regulators feature high-withstand voltage, low current consumption, and high-accuracy output voltage. These regulators consist of a built-in overcurrent protection circuit to limit the overcurrent of the output transistor, and a built-in thermal shutdown circuit to limit heat. The S-19222xA voltage regulators operate within an input voltage range from 3V to 36V. Typical applications include constant-voltage power supply for electrical applications for vehicle interiors and constant-voltage power supply for home electrical appliances.
