MAX6034AEXR25+T

Overview

The MAX6034AEXR25+T is a precision, micropower, low-dropout series voltage reference housed in a 3-pin SC70 surface-mount package. It delivers a fixed output voltage of 2.500V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 30ppm/°C. The device operates within an input voltage range of 2.7V to 5.5V, drawing a typical quiescent supply current of 90µA. It can source up to 1mA and sink up to 200µA of load current while maintaining stability with capacitive loads ranging from 0 to 1µF without requiring external compensation components.

Feature Summary

• Proprietary curvature-correction circuitry combined with laser-trimmed thin-film resistors ensures high precision and low temperature drift.
• Series-mode architecture provides supply current virtually independent of input voltage variations, eliminating the need for external biasing resistors.
• Internally compensated design allows stable operation with zero to 1µF of load capacitance, removing the requirement for external output capacitors.

Applications

• Hand-Held Equipment
• Data-Acquisition Systems
• Industrial and Process Control Systems
• Battery-Operated Equipment
• Hard-Disk Drives

Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code AJI on the SC70-3 package against official documentation. Confirm the suffix +T indicates tape-and-reel packaging and ensure the A grade matches the required ±0.2% accuracy specification. Cross-reference the part number with authorized distributors to confirm availability status and compliance with RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require a precise voltage reference in a miniature SC70 package. It is suitable for battery-powered applications due to its ultra-low supply current and independence from supply voltage fluctuations. Ensure the input voltage remains above the minimum dropout threshold relative to the 2.5V output under all operating conditions and load currents.
