MAX6102EUR

Overview

The MAX6102EUR is a low-cost, micropower, low-dropout voltage reference from the MAX6100–MAX6107 series. It provides a fixed output of 2.5V with an initial accuracy of ±0.4% and a temperature coefficient of 75ppm/°C. The device operates within an input voltage range of 2.5V to 12.6V and draws a maximum quiescent supply current of 125µA. It supports a load current of 5mA and functions reliably over an extended temperature range of -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount case, it requires no external output capacitor.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high precision and stability.
• Capable of driving capacitive loads without oscillation, eliminating the need for external output capacitors.
• Low dropout voltage allows operation with minimal headroom between input and output voltages.
• Micropower consumption design extends battery life in portable applications.

Applications

• Portable battery-powered systems
• Notebook computers
• Personal Digital Assistants (PDAs) and GPS devices
• Digital Multimeters (DMMs)
• Cellular phones

Procurement Notes

Verify the specific suffix against the manufacturer's official part numbering system to confirm package type, temperature grade, and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements if mandated by your assembly process. Cross-reference the datasheet revision date to confirm technical parameters match your design constraints before finalizing procurement.

Selection Notes

Select this component when a fixed 2.5V reference is required in space-constrained designs utilizing the SOT-23-3 package. It is suitable for applications demanding low power consumption and stable performance under varying load conditions. Consider the 75ppm/°C temperature coefficient for thermal environments outside standard industrial ranges. Verify that the 5mA output current capability meets the reference drive requirements of the downstream circuitry.

Part Context

The MAX6102EUR belongs to the MAX6100–MAX6107 family of voltage references manufactured by Analog Devices Inc./Maxim Integrated. This series offers various fixed output voltages including 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V.
