This IC 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.
It has a high operation voltage of 66 V, making it compatible with 12 V, 24 V, and 48 V automotive auxiliary battery systems, and it can be operated at a low consumption current of 2.0 μA typ. It also features a built-in overcurrent protection circuit to limit overcurrent of the output transistor, a built-in thermal shutdown circuit to limit heat, and a built-in open-loop protection circuit to control output voltage overvoltage.

Thermal simulation service
ABLIC Inc. offers a “thermal simulation service” which supports the thermal design in conditions when our power management ICs are in use by customers. Our thermal simulation service will contribute to reducing the risk in the thermal design at customers development stage.
For more information regarding our thermal simulation service, contact our sales representatives.

FIT rate calculation
ABLIC Inc. offers FIT rate calculated based on actual customer usage conditions in order to support customer functional safety design.
For more information regarding our FIT rate calculation, contact our sales representatives.

Caution: This product can be used in vehicle equipment and in-vehicle equipment. Before using the product for these purposes, it is imperative to contact our sales representatives.

  • Constant-voltage power supply for electrical application for vehicle interior

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.
