ISL78301FVEBZ-T7A

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

The ISL78301FVEBZ-T7A is a linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It is designed for automotive applications and features a fixed 5V output with a maximum continuous current of 150mA. The device operates within an input voltage range of up to 40V and maintains low quiescent current consumption. It is housed in an 8-lead SOIC package with an exposed pad (SOIC-EP). The component is specified for operation across the automotive temperature range, ensuring reliability in demanding environments.

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

Verify the specific suffix FVEBZ-T7A against official Renesas documentation to confirm pinout, thermal characteristics, and exact output tolerance. Ensure the source document explicitly lists this part number as active or available, as some variants in the ISL78301 family may have different statuses. Cross-reference the package type and lead finish requirements with your manufacturing specifications before ordering.

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

Select this component when a fixed 5V rail is required for automotive-grade circuits with moderate current demands up to 150mA. Consider its 40V input rating for systems with significant voltage transients. Evaluate thermal dissipation requirements based on the voltage drop between input and output currents. Compare against adjustable LDOs if variable output voltage flexibility is needed instead of a fixed rail.

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

The ISL78301 belongs to Renesas' portfolio of automotive linear regulators, complementing other devices like the ISL78307 series. It serves as a dedicated solution for 5V distribution in vehicles, distinct from switching regulators due to its low noise profile. This family supports various output configurations and current ratings tailored for different ECU power architectures.

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

Check for direct cross-references in Renesas replacement guides. Verify compatibility with existing PCB footprints, particularly the SOIC-EP package dimensions. Ensure electrical parameters such as dropout voltage and thermal resistance match the original design constraints.
