MAX1820YEBC

Overview

The MAX1820YEBC is a single-output linear voltage regulator IC manufactured by Analog Devices Inc./Maxim Integrated. Designed for DDR memory and WCDMA applications, it features an input voltage range of 2.6V to 5.5V and an adjustable output voltage range of 0.4V to 3.4V. The device provides one output channel and operates within a temperature range of -40°C to 85°C (TA). It is housed in a 10-WFBGA CSPBGA package with surface mount mounting type.

Feature Summary

• Single-output DDR voltage regulator design
• Wide input voltage capability from 2.6V to 5.5V
• Adjustable output voltage spanning 0.4V to 3.4V
• Industrial operating temperature range

Applications

• DDR memory power supply
• WCDMA cellular phone systems
• Converter applications requiring stable low-voltage regulation

Procurement Notes

Verify the specific suffix and manufacturer designation when ordering, as listings may vary between Maxim Integrated and Analog Devices Inc. Ensure the package type matches the 10-WFBGA CSPBGA requirement. Confirm the active product status and temperature grade before finalizing procurement to avoid compatibility issues with existing designs.

Selection Notes

Select this component when a dedicated linear regulator for DDR memory or WCDMA interfaces is required. The wide input range accommodates various battery or system voltages. The adjustable output allows precise voltage setting for different memory standards. Consider the thermal performance and package size constraints inherent to the 10-WFBGA form factor during PCB layout.

Part Context

This part belongs to the MAX1820 family of voltage regulators. Variants such as MAX1820YEBC-T exist, often differing only in tape-and-reel packaging. Other related parts like MAX1820YEUB are switching regulators, which differ fundamentally in topology and application compared to this linear regulator series.

Replacement Considerations

Direct substitutes include MAX1820YEBC-T for identical functionality with reel packaging. Cross-reference with other DDR-specific linear regulators if pinout compatibility is not required. Verify that replacement parts support the same 2.6V-5.5V input and 0.4V-3.4V output ranges.
