ZXRE160AFT4-7

Overview

The ZXRE160AFT4-7 is a 5-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It features a low reference voltage of 0.6V and an initial tolerance of ±0.5%. The device operates within an input voltage range of 2V to 18V and supports an output voltage range from 0.2V to 18V. Maximum cathode current is 15mA, with a supply current of approximately 1mA. It utilizes an X2-DFN1520H4-6 package and functions across an ambient temperature range of -40°C to +125°C.

Feature Summary

• Enhanced adjustable precision shunt regulator design offering excellent temperature stability
• Low 0.6V feedback pin enables regulation of rails down to 0.6V
• Separate input and open-collector output pins allow operation as low-dropout regulators
• High power supply rejection ratio for stable performance in noisy environments

Applications

• Isolated DC-DC converters
• Core voltage POL converters for microprocessors and DSPs
• Low Voltage Low-Dropout linear regulators
• Shunt regulators
• Adjustable voltage reference

Procurement Notes

Verify the specific ordering suffix FT4-7 corresponds to the X2-DFN1520H4-6 package configuration. Confirm that the A grade designation matches the required ±0.5% initial tolerance specification. Ensure compliance with RoHS and Halogen-free requirements if mandated by project standards. Cross-reference the datasheet revision DS35688 Rev. 2 for accurate electrical characteristics.

Selection Notes

Select this component when precise regulation at low voltages near 0.6V is required. The separate input and output terminals facilitate complex feedback topologies involving opto-couplers. Consider the thermal dissipation capabilities of the DFN package relative to the maximum 15mA sink current. Verify that the operating voltage range aligns with the auxiliary rail availability in the target circuit design.

Part Context

This part belongs to the ZXRE160 product line, which serves as an enhancement to the ZXRE060 series. It is designed specifically for comparator mode applications and isolated power supplies. The family includes variants in SC70/SOT353, TSOT25, and DFN packages, catering to different space constraints while maintaining consistent electrical performance profiles.

Replacement Considerations

ZXRE060AFT4-7: Direct functional substitute with slightly higher reference voltage (0.2V) and lower accuracy.
