MAX6133A50+T

Overview

The MAX6133A50+T is a high-precision, low-power series voltage reference featuring a maximum temperature coefficient of 3ppm/°C and an initial accuracy of ±0.04%. It provides a fixed 5V output with a quiescent supply current of 40µA and supports source currents up to 15mA. The device operates within a wide input voltage range of 2.7V to 12.6V and maintains stability with capacitive loads up to 100µF. It is housed in an 8-pin SO package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Ultra-low temperature coefficient for enhanced thermal stability
• High initial accuracy guaranteed by laser-trimmed thin-film resistors
• Low dropout voltage capability for efficient power usage
• Minimal quiescent current consumption independent of supply voltage

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 'AASA' confirms the 8-pin SO package variant. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure the final digit '50' matches the required 5.000V output specification. Cross-reference the manufacturer's latest datasheet for any updates to electrical characteristics or pin configurations before integration.

Selection Notes

Select this component when system requirements demand high precision combined with minimal power consumption. The low dropout voltage allows operation from single-cell batteries or tight supply margins. Verify that the 15mA source current capability meets load demands without requiring external buffering. Consider the 8-pin SO package dimensions for PCB layout constraints.

Part Context

This part belongs to the MAX6133 family of bandgap voltage references designed for portable and communication applications. The series-mode architecture offers superior efficiency compared to shunt references. The A-grade classification ensures tighter performance tolerances suitable for demanding measurement environments.

Replacement Considerations

Direct substitutes include other MAX6133 variants with different output voltages or packages, such as MAX6133AASA25+T. Verify compatibility regarding package footprint and electrical specifications before substitution.
