Automotive, 105°C Operation, 50 V Input, 200 mA Voltage Regulator S-19200A/BxxH Series

The S-19200A/BxxH 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.
High heat radiation TO-252-5S(A) and HSOP-6 packages enable 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.
