AUTOMOTIVE, 125°C OPERATION,
36 V INPUT, 250 mA VOLTAGE REGULATOR
The S-19212B/DxxA 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, and has a built-in
ON / OFF circuit.
The S-19212B/DxxA Series operates at the maximum operation voltage of 36 V and a low current consumption of
6.5 μA typ., and has a built-in low on-resistance output transistor which provides a very small dropout voltage and a large
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.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the
