ZXRD060AFK-7

Overview

The ZXRD060AFK-7 is a dual adjustable precision shunt regulator in a DFN2626P10 package. It features a low 0.6V reference voltage, enabling regulation of rails down to 0.2V. The device operates with an input voltage range of 2V to 18V and supports output currents up to 15mA. It offers high accuracy with a feedback voltage tolerance of ±0.5% at 25°C for the 'A' grade. The open-collector outputs allow operation at low voltages, making it suitable for isolated DC-DC converters and core voltage POL converters.

Feature Summary

• Dual independent channels with separate inputs and outputs
• Low 0.6V internal reference voltage for ultra-low dropout operation
• High precision feedback voltage tolerance of ±0.5%
• Open-collector outputs capable of operating down to 0.2V

Applications

• Isolated DC-DC converters using opto-couplers
• Core voltage POL converters for microprocessors/DSPs/PLDs
• Low voltage LDO regulators
• Shunt regulators requiring low dropout performance

Procurement Notes

Verify the ordering suffix 'FK' corresponds to the DFN2626P10 package and '-7' indicates tape and reel packaging. Confirm the 'A' designation ensures the tighter ±0.5% feedback voltage tolerance specification compared to the standard grade. Ensure compatibility with the required ambient temperature range of -40°C to 125°C for your specific application environment.

Selection Notes

Select this component when a low reference voltage is critical for minimizing dropout in shunt regulator configurations. The dual-channel architecture allows simultaneous regulation of two distinct rails from a single package. Consider the ±0.5% tolerance if system accuracy requirements exceed standard grades. Verify that the 15mA maximum output current meets the load requirements of the controlled rail.

Part Context

This part belongs to the ZXRD060 family of dual adjustable precision shunt regulators manufactured by Diodes Incorporated. The family is designed to simplify the design of isolated power supplies and low-dropout regulators. Unlike traditional shunt references, these devices feature separate input and output pins, facilitating flexible circuit topologies for modern processor core voltage applications.

FAQ

What is the minimum output voltage the ZXRD060AFK-7 can regulate?

The device can regulate output voltages as low as 0.2V due to its low 0.6V reference and open-collector output structure.

How does the 'A' suffix affect the electrical characteristics?

The 'A' suffix indicates a tighter feedback voltage tolerance of ±0.5% at 25°C, compared to ±1% for the standard grade.
