Automotive, 105°C Operation, 50 V Input, 200 mA Voltage Regulator S-1142C/DxxH Series

S-1142C/DxxH 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-1142C/DxxH 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.

Parts List

  • U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
    however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
  • Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
  • These descriptions may be different from the actual product name and parameter.
    Please confirm the product name and specifications with the data sheet again.
