ZXRD060FK-7

Overview

The ZXRD060FK-7 is a dual adjustable precision shunt regulator in a DFN2626P10 package. It features a nominal feedback voltage of 0.6V with ±1% tolerance at 25°C. The device supports an input voltage range of 2V to 18V and regulates output voltages from 0.2V to 18V. Maximum output current is 15mA, with typical temperature drift of 45mV over the -40°C to 125°C range. Operating ambient temperature spans -40°C to 125°C.

Feature Summary

• Dual independent channels with separate inputs and outputs for isolated regulation
• Low 0.6V reference voltage enables operation down to 0.2V output
• High accuracy feedback voltage with low temperature drift
• Open-collector output suitable for opto-coupler feedback loops

Applications

• Isolated DC-DC converters using opto-couplers
• Core voltage POL converters for microprocessors and DSPs
• Low-voltage low-dropout line regulators
• Shunt regulators requiring precise voltage references

Procurement Notes

Verify the ordering suffix FK-7 corresponds to the DFN2626P10 package and tape & reel quantity. Confirm the specific tolerance grade matches design requirements, as the base model offers standard grading while the A variant provides tighter specifications. Ensure supply chain documentation aligns with the manufacturer's green policy standards.

Selection Notes

Select this component when dual-channel isolation or low-voltage regulation below standard reference thresholds is required. The wide input range allows powering from auxiliary rails while controlling master rails. Consider thermal dissipation limits in the small DFN package if operating near maximum current ratings.

Part Context

This part belongs to Diodes Incorporated's ZXRD series of precision shunt regulators. It shares architectural similarities with single-channel variants but integrates two independent regulation loops into a compact footprint. The series targets applications demanding high accuracy and stability in space-constrained designs.

FAQ

How does the open-collector output benefit isolated power supplies?

It allows the output to operate down to 0.2V, facilitating direct interfacing with opto-couplers in feedback loops without requiring additional level-shifting components.

What is the difference between ZXRD060 and ZXRD060A?

The ZXRD060A offers a tighter feedback voltage tolerance of ±0.5% compared to the standard ±1% tolerance of the ZXRD060.
