S-19243xxxH Series
www.sii-ic.com
FOR AUTOMOTIVE 105°C OPERATION LOW DROPOUT HIGH OUTPUT CURRENT
CMOS VOLTAGE REGULATOR WITH SOFT-START FUNCTION
© SII Semiconductor Corporation, 2016
Rev.3.0_00
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 SII Semiconductor Corporation is indispensable.

*1. Connect the heat sink of backside at shadowed area to the board, and set electric potential open or GND.
However, do not use it as the function of electrode.
*2. Although pins of number 1 and 2 are connected internally, be sure to short-circuit them nearest in use.
*3. The NC pin is electrically open.
The NC pin can be connected to the VIN pin or the VSS pin.
*4. Connect a capacitor between the SSC pin and the VSS pin.
The soft-start time at power-on and at the time when the ON / OFF pin is set to ON can be adjusted according to
the capacitance.
