MAX1821EUB-TG069

Overview

The MAX1821EUB-TG069 is a linear regulator IC designed for WCDMA applications, featuring a 600mA output current capability. It utilizes a compact 10-lead μMAX package (TFSOP/MSOP) with a width of 3.00mm. The device is RoHS compliant and lead-free. It is engineered to provide low noise performance and high Power Supply Rejection Ratio (PSRR), making it suitable for sensitive RF circuits requiring stable voltage regulation in small form factors.

Feature Summary

• Optimized for low noise and high PSRR in WCDMA systems
• Compact 10-pin surface-mount packaging for space-constrained designs

Applications

• WCDMA mobile phone power supplies
• RF circuit voltage regulation
• Portable electronic devices requiring low-noise LDOs

Procurement Notes

Verify the exact suffix TG069 against official Analog Devices documentation to confirm specific tape-and-reel or tube packaging configurations. Ensure compatibility with 10-TFSOP or 10-MSOP footprints during PCB layout. Confirm RoHS compliance status for your region's regulatory requirements before finalizing procurement.

Selection Notes

Select this component when designing for WCDMA architectures that demand minimal output noise and high supply rejection. The 600mA rating suits moderate load currents. Consider the 10-lead μMAX package constraints for thermal management and board space. Validate input-output voltage differentials to ensure proper linear regulation operation within specified limits.

Part Context

This part belongs to the Maxim Integrated line of low-dropout regulators, now under Analog Devices. It targets the wireless communication sector, specifically addressing the stringent noise and rejection requirements of third-generation cellular standards. The μMAX package represents a standard footprint for compact consumer electronics from that era.

Replacement Considerations

Check for direct pin-compatible successors in the ADI portfolio. Verify if newer generations offer improved thermal performance or updated packaging options while maintaining the 600mA WCDMA specification.
