MAX6133BASA25+

Overview

The MAX6133BASA25+ is a high-precision, low-power series voltage reference with a fixed 2.500V output. It features a maximum temperature coefficient of 5ppm/°C and an initial accuracy of ±0.08%. The device operates within a supply voltage range of 2.7V to 12.6V, consuming typically 40µA of quiescent current. It provides up to 15mA of source current capability and exhibits excellent line and load regulation. Packaged in an 8-pin SOIC-Narrow format, it supports operation from -40°C to +125°C.

Feature Summary

• Low power consumption with virtually independent supply current
• High precision performance with laser-trimmed thin-film resistors
• Low dropout voltage for efficient operation near minimum input levels
• Compact surface-mount packaging suitable for space-constrained designs

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 'B' indicates the B-grade accuracy class and 'SA' denotes the SO package variant. Confirm the final digit '25' corresponds to the 2.5V output option. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement specifications.

Selection Notes

Select this component when a stable 2.5V reference is required with minimal static current draw. Ensure the input voltage remains above the minimum dropout threshold under all load conditions. Consider the thermal hysteresis specification if the device undergoes significant temperature cycling during operation.

Part Context

This part belongs to the MAX6133 family of bandgap voltage references designed for portable and communication applications. It utilizes post-package trimming to guarantee tight accuracy specifications. The series-mode architecture distinguishes it from shunt references by offering superior efficiency and reduced external component requirements.
