FOR AUTOMOTIVE 105°C OPERATION LOW DROPOUT HIGH OUTPUT CURRENT
CMOS VOLTAGE REGULATOR WITH SOFT-START FUNCTION
© SII Semiconductor Corporation, 2016
The S-19254xxxH 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. Also, the S-19254xxxH 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 SII Semiconductor Corporation is indispensable.
