FOR AUTOMOTIVE 125°C OPERATION HIGH-WITHSTAND VOLTAGE LOW DROPOUT
CMOS VOLTAGE REGULATOR
Rev.1.0_01
The S-19212 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-19212 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 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.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in
the purpose, contact to SII is indispensable.

Caution The above connection diagram and constants will not guarantee successful operation. Perform
thorough evaluation using an actual application to set the constants.
Condition of Application
Input capacitor (CIN): A ceramic capacitor with capacitance of 1.0 μF or more is recommended.
Output capacitor (CL): A ceramic capacitor with capacitance of 1.0 μF to 100 μF is recommended.
Caution Generally, in a voltage regulator, an oscillation may occur depending on the selection of the external
parts. Perform thorough evaluation including the temperature characteristics with an actual
application using the above capacitors to confirm no oscillation occurs.
Selection of Input Capacitor (CIN) and Output Capacitor (CL)
The S-19212 Series requires CL between the VOUT pin and the VSS pin for phase compensation. The operation is
stabilized by a ceramic capacitor with capacitance of 1.0 μF to 100 μF. When using an OS capacitor, a tantalum
capacitor or an aluminum electrolytic capacitor, the capacitance also must be 1.0 μF to 100 μF. However, an oscillation
may occur depending on the equivalent series resistance (ESR).
Moreover, the S-19212 Series requires CIN between the VIN pin and the VSS pin for a stable operation.
Generally, an oscillaiton may occur when a voltage regulator is used under the conditon that the impedance of the
power supply is high.
Note that the output voltage transient characteristics varies depending on the capacitance of CIN and CL and the value
of ESR.
Caution Perform thorough evaluation including the temperature characteristics with an actual application to
select CIN and CL.
