S-19213 Series AUTOMOTIVE, 125C OPERATION, www.ablic.com 36 V INPUT, 500 mA VOLTAGE REGULATOR ABLIC Inc., 2019-2020 Rev.1.3 00 The S-19213 Series developed by using high-withstand voltage CMOS process technology, is a positive voltage regulator with a high-withstand voltage, low current consumption and high-accuracy output voltage. The S-19213 Series operates at the maximum operation voltage of 36 V and a low current consumption of 5.0 A typ. and has a built-in low on-resistance output transistor, which provides a very small dropout voltage and a large output current. In addition to the type in which output voltage is set inside the IC, the type for which output voltage can be set via an external resistor is added to a lineup. Also, 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.
