MAX8515AEZK-T

Overview

The MAX8515AEZK-T is a wide-input shunt voltage regulator designed for isolated DC-to-DC converters. It features a 0.6V reference with ±0.5% initial accuracy at +25°C and ±1% across the -40°C to +85°C temperature range. The device supports an input voltage range from 1.7V to 28V and can sink up to 20mA while maintaining regulation down to 0.2V output. It offers a dynamic output impedance of 0.2Ω and is housed in a space-saving SC-70 package.

Feature Summary

• Provides high-accuracy 0.6V shunt regulation suitable for low-voltage isolated converter outputs
• Features separated supply and feedback inputs allowing independent biasing from the converter output
• Capable of directly driving optocouplers for isolation feedback loops
• Maintains stable operation with a low dynamic output impedance

Applications

• Isolated DC-to-DC converters
• Network, telecom, and cellular base station power supplies
• Low-dropout linear regulators
• Shunt regulator adjustable voltage references

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and specific tape-and-reel packaging requirements prior to ordering. Ensure design compatibility with the 1.7V to 28V input range and 20mA sinking capability. Review latest datasheet revisions for any pinout or electrical parameter updates before finalizing procurement specifications.

Selection Notes

Select this component when precise 0.6V regulation is required for isolated power stages. The ±0.5% initial accuracy makes it suitable for high-precision applications. Consider the separate input stage if the bias supply differs from the regulated output voltage. The SC-70 package is ideal for space-constrained designs requiring direct optocoupler integration without additional level-shifting circuitry.

Part Context

This part belongs to the MAX8515 family of wide-input shunt regulators manufactured by Analog Devices (Maxim Integrated). These devices are engineered to simplify overvoltage protection and voltage regulation in isolated power systems. The AE suffix denotes the higher precision grade compared to the standard MAX8515 variant.

Replacement Considerations

The MAX8515A serves as the lower-precision alternative within the same family. Verify functional equivalence regarding input voltage ranges and sinking capabilities before substitution.
