HIGH-WITHSTAND VOLTAGE LOW CURRENT CONSUMPTION
LOW DROPOUT CMOS VOLTAGE REGULATOR
The S-1142C/D Series, developed by using high-withstand voltage CMOS technology, is a positive voltage regulator
with a high-withstand voltage, low current consumption, and high-accuracy output voltage.
The S-1142C/D 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 protection circuit prevents the load current from exceeding the current capacity 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.
