ISL78307FBECZ-T7A

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

The ISL78307FBECZ-T7A is a low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It features an adjustable output voltage range and provides a maximum output current of 50 mA. The device is housed in an 8-lead Small Outline Integrated Circuit with an exposed pad (8-SOIC-EP) package. This component is designed to deliver stable regulated power for sensitive electronic circuits requiring precise voltage control.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Provides a positive adjustable output voltage capability
• Operates as a low-noise linear regulator for clean power delivery
• Features high Power Supply Rejection Ratio (PSRR) performance

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

• Automotive sensor signal conditioning
• Low noise analog circuit biasing
• Portable electronic device power management

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

Verify the specific suffix 'T7A' against the official datasheet to confirm tape and reel packaging specifications. Confirm that the adjustable output variant matches the design requirements, as fixed voltage versions exist within the same family. Check for end-of-life status or alternative recommendations from the manufacturer due to potential discontinuation.

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

Select this component when an adjustable output voltage is required alongside low noise characteristics. Ensure the input-to-output differential voltage remains within the specified dropout limits for the desired load current. Verify thermal dissipation capabilities given the SOIC-EP package and the 50 mA output rating.

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

This part belongs to the ISL78307 series of automotive-grade LDO regulators. The series is characterized by low quiescent current and high PSRR, making it suitable for noise-sensitive applications. The FBECZ suffix indicates the adjustable output version, distinguishing it from fixed voltage variants like the FBEAZ (3.3V) or FBEBZ (5V).

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

Consult the Renesas product change notification database for officially confirmed substitute part numbers. Direct pin-compatible replacements may include other adjustable LDOs from the same family if available, but cross-referencing electrical parameters is essential.
