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
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.
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.
ABLIC Inc. offers FIT rate calculated based on actual customer usage conditions in order to support customer functional
safety design.
