Automotive ICs

Automotive, 125°C Operation, 36 V Input, 200 mA Voltage Regulator with Reset Function S-19311 Series

The S-19311 Series, developed by using high-withstand voltage CMOS technology, is a positive voltage regulator with the reset function, which has high-withstand voltage and high-accuracy output voltage. This IC has a built-in low on-resistance output transistor which provides a small dropout voltage and a large output current. 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.
High heat radiation TO-252-5S(A) and HSOP-8A packages enable high-density mounting.

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.
For more information regarding our thermal simulation service, contact our sales representatives.

Caution: This product can be used in vehicle equipment and in-vehicle equipment. Before using the product for these purposes, it is imperative to contact our sales representatives.
