FOR AUTOMOTIVE 105C OPERATION LOW DROPOUT HIGH OUTPUT CURRENT
CMOS VOLTAGE REGULATOR WITH SOFT-START FUNCTION
Rev.3.1_01
The S-19243xxxH Series developed by using high-withstand voltage CMOS process technology, is a positive voltage
regulator with high-accuracy output voltage and high output current.
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. In addition to the type in which output voltage is set inside the IC, the type for which output voltage
can be set via an external resistor is added to a lineup. Also, the S-19243xxxH Series includes the soft-start function to
adjust the output voltage rising time at power-on or at the time when the ON / OFF pin is set to ON.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in
the purpose, contact to ABLIC Inc. is indispensable.
