ZXRE060AFT4-7

Overview

The ZXRE060AFT4-7 is a 5-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It features an open-collector output capable of operating from 0.2V to 18V, with a regulated output voltage set via two external divider resistors. The device utilizes a low 0.6V feedback reference pin and operates within an input voltage range of 2V to 18V. It provides an initial tolerance of ±0.5% at +25°C and functions across a temperature range of -40°C to +125°C. The component is housed in a 6-DFN1520H4 package.

Feature Summary

• Separates input supply from the open-collector output to facilitate low-dropout linear regulator designs.
• Enables regulation of rails as low as 0.6V using the dedicated low-voltage feedback pin.
• Provides high accuracy with an initial tolerance of ±0.5% for the A-grade variant.

Applications

• Isolated DC-DC converters
• Core voltage POL (Point-of-Load) converters
• Low voltage low-dropout linear regulators

Procurement Notes

Verify the specific suffix FT4-7 confirms the DFN1520H4-6 package and tape-and-reel packing configuration. Confirm the 'A' grade designation matches the required ±0.5% initial tolerance specification. Check current availability status as the datasheet indicates this series is not recommended for new design.

Selection Notes

Select this component when a low-profile surface-mount solution is required for precise shunt regulation. Ensure the application supports the 2V to 18V input range and requires an open-collector output interface. Verify that the 6-pin DFN1520H4-4 footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the ZXRE060 family of adjustable precision shunt regulators. It serves as a space-saving alternative to traditional references, available in SC70-5, TSOT23-5, and DFN packages. The device simplifies isolated power supply designs by allowing the control of master rails distinct from the auxiliary supply powering the device.

Replacement Considerations

The datasheet explicitly states that the ZXRE060 is not recommended for new designs and recommends using the ZXRE160 instead.
