ISL78307FBECZ

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

The ISL78307FBECZ is a linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides a single positive adjustable output voltage with a maximum output current of 50 mA. The device operates within an input voltage range of 6 V to 40 V and is designed for automotive applications, supporting an extended operating temperature range from -40°C to +125°C. It features a low quiescent current of 18 µA and utilizes an 8-lead SOIC package with an exposed pad for thermal management.

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

Verify the specific suffix 'FBECZ' against the official Renesas datasheet to confirm the adjustable output variant. Confirm RoHS compliance status as indicated in the product specifications. Check for end-of-life notices or obsolescence warnings prior to procurement, as availability may be limited for discontinued components.

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

Select this component when an adjustable LDO is required for automotive-grade applications. Ensure the input voltage remains between 6 V and 40 V. Verify that the 50 mA load current does not exceed the device's thermal limits within the intended operating temperature range. Consider the SOIC-8EP package for adequate heat dissipation.

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

This part belongs to the ISL78307 series of always-on LDO regulators. The series is characterized by high reliability and low noise, specifically tailored for automotive electronics. The FBECZ designation indicates the adjustable output version, distinct from fixed voltage variants like the 3.3V or 5V models within the same family.

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

Consult the official Renesas replacement guide for direct substitutes. Potential alternatives include other automotive-grade adjustable LDOs with similar 40V input ratings and 50mA output capabilities, ensuring pin compatibility and thermal performance match.
