S-19213B80A-V5T2U7

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The S-19213B80A-V5T2U7 is an automotive-grade positive voltage regulator from the S-19213 Series, manufactured by ABLIC Inc. It utilizes high-withstand voltage CMOS process technology to operate at a maximum input voltage of 36 V and withstand 45 V load dump events. The device provides a fixed internally set output voltage of 8.0 V with an accuracy of ±1.5% across the junction temperature range of −40°C to +125°C. It supports an output current of up to 500 mA when the input voltage exceeds the output voltage by at least 1.0 V. Typical current consumption during operation is 5.0 μA, while power-off consumption is 0.1 μA. The component is housed in a TO-252-5S(A) package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify that the specific part number matches the required internal output voltage setting and package type. Confirm compliance with AEC-Q100 Grade 1 requirements for your target application environment. Contact sales representatives for thermal simulation services and FIT rate calculations to support functional safety design and thermal management planning before finalizing procurement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for designs requiring high input voltage tolerance and low quiescent current. Ensure the input voltage remains within the 2.8 V to 36.0 V range and that the output current does not exceed limits defined by power dissipation constraints. Use ceramic capacitors of 1.0 μF or more for both input and output stabilization. Verify that the parasitic diode between VIN and VOUT does not cause reverse current issues in the system architecture.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the S-19213 Series of automotive voltage regulators designed for 125°C operation. The series offers both internally set and externally adjustable output voltage options. The B suffix indicates a positive logic ON/OFF pin configuration, while V5T2 specifies the TO-252-5S(A) package with tape packing. The U suffix denotes lead-free and halogen-free environmental compliance.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Cross-reference with other S-19213 variants such as S-19213B50A-V5T2U7 for different fixed voltages or S-19213B00A-V5T2U7 for adjustable outputs. Ensure any substitute maintains the same package footprint and electrical characteristics including input voltage range and output current capabilities.
