S-1142A/BxxH 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. S-1142A/BxxH 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.
Caution: Before using the product in automobile control unit or medical equipment, it is imperative to contact our sales representatives.
