HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION
LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.3.0
_00
The S-1142 Series, developed based on high-withstand voltage CMOS process, is a positive voltage regulator with a
high-withstand voltage, low current consumption, and high output voltage accuracy. The S-1142 Series operates at a high
maximum operating voltage of 50 V and a low current consumption of 4.0
μA
typ. In addition to a built-in low on-resistance
transistor which provides a very small dropout voltage and a large output current, this voltage regulator also has a built-in
ON / OFF circuit.
An overcurrent protector prevents the load current from exceeding the capacitance of the output transistor, and a built-in
thermal shutdown circuit prevents damage caused by heat.
A high heat radiation HSOP-6 package enables high-density mounting.
