MAX6133BASA30+T

Overview

The MAX6133BASA30+T is a high-precision, low-power series voltage reference featuring bandgap technology and laser-trimmed thin-film resistors. It delivers a fixed 3.000V output with a maximum initial accuracy of ±0.08% and a temperature coefficient of 5ppm/°C across the -40°C to +125°C range. The device operates on a supply voltage from 3.2V to 12.6V, consuming only 40µA of quiescent current. It provides up to 15mA of source current capability with a maximum dropout voltage of 200mV.

Feature Summary

• Low power consumption with virtually supply-voltage-independent quiescent current
• High precision performance utilizing laser-trimmed thin-film resistors
• Low dropout voltage operation for efficient power usage
• Excellent line and load regulation specifications

Applications

• Precision regulators
• A/D and D/A converters
• Power supplies
• High-accuracy industrial and process control systems
• Hand-held instruments

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the B-grade designation matches the required ±0.08% accuracy specification for your design. Ensure the input voltage range supports the minimum 3.2V requirement for the 3.000V output variant. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this part when a fixed 3.000V reference is needed with tight accuracy constraints. The B-grade offers slightly looser accuracy than the A-grade but maintains robust performance. Consider the SO package dimensions against available board space. Evaluate the 15mA source current capability against peak load requirements to ensure stability under transient conditions.

Part Context

This component belongs to the MAX6133 family of low-dropout voltage references. It shares core architecture with other variants in the series, differing primarily in output voltage options and grade-specific accuracy tolerances. The family utilizes BiCMOS processing and includes both µMAX and SO package options for flexible integration into various electronic designs.

Replacement Considerations

Direct substitutes within the same family include MAX6133AASA30+ for tighter accuracy or MAX6133BASA25+/MAX6133BASA41+ for different voltage outputs. Verify pin compatibility and thermal characteristics when replacing with other Maxim Integrated voltage references.
