MAX6133AASA50+T

Overview

The MAX6133AASA50+T is a high-precision, low-power series voltage reference featuring bandgap technology and laser-trimmed thin-film resistors. It delivers a fixed 5V output with an initial accuracy of ±0.04% maximum and a temperature coefficient of 3ppm/°C maximum. The device operates within a supply voltage range of 2.7V to 12.6V, consuming only 40µA of quiescent current. It provides a source-current capability of up to 15mA and maintains stability with capacitive loads up to 100µF. Packaged in an 8-pin SOIC, it functions reliably across temperatures from -40°C to +125°C.

Feature Summary

• Ultra-low temperature coefficient ensures minimal drift over wide operating ranges
• High initial accuracy maintained through post-package trimming and laser-stable resistors
• Low dropout voltage allows operation with minimal input-to-output voltage difference
• Minimal supply current consumption maximizes efficiency in battery-powered systems

Applications

• Precision regulators for sensitive analog circuits
• Reference sources for A/D and D/A converters
• High-accuracy industrial and process control instrumentation
• Hand-held instruments requiring extended battery life

Procurement Notes

Verify the specific suffix '50' confirms the 5.000V output option. Confirm the 'A' grade indicates the highest accuracy tier (±0.04%). Ensure the 'SA' designation matches the required 8-pin SO package. Check RoHS compliance status if environmental regulations apply. Validate that the '+T' tape-and-reel packaging meets assembly requirements.

Selection Notes

Select this component when system design demands exceptional long-term stability and low noise. The low quiescent current makes it suitable for portable applications where power conservation is critical. Verify that the input voltage remains above the minimum specified threshold to ensure proper regulation. Consider the thermal hysteresis characteristics if the device undergoes significant temperature cycling during operation.
