Automotive, 125°C Operation, 50 V Input, 200 mA Voltage Regulator S-19200A/BxxA Series

Available Applications
Automotive ICs are categorized according to their application. The following symbols indicate the types of applications for which an IC can be used.
Meter, body, headlamp, ITS, etc.
Accessory, car navigation, car audio system, etc.

The S-19200A/BxxA Series, developed by using high-withstand voltage CMOS technology, is a positive voltage regulator with a high-withstand voltage, low current consumption, and high-accuracy output voltage.
The S-19200 Series operates at a high maximum operating voltage of 50 V and a low current consumption of 4.0 µA typ.
In addition to a built-in low on-resistance transistor which provides a very small dropout voltage and a large output current, this voltage regulator also has a built-in ON / OFF circuit.
An overcurrent protection circuit prevents the load current from exceeding the current capacity of the output transistor, and a built-in thermal shutdown circuit prevents damage caused by heat.
A high heat radiation TO-252-5S(A) package enables high-density mounting.

Caution: This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the purpose, contact to SII is indispensable.
