Product details
Overview
The MAX6106EUR-T from Maxim Integrated is a 2.048V, low-dropout (LDO), micropower series-mode voltage reference in a 3-pin SOT23 package. It delivers ±0.4% initial accuracy, 75ppm/°C max temperature coefficient, and operates from 2.5V to 12.6V input across –40°C to +85°C. Designed for precision ADC/DAC biasing in portable instrumentation and battery-powered data acquisition systems, it sources up to 5mA and sinks 2mA with only 90µA quiescent current.
For engineers reviewing the MAX6106EUR-T datasheet, MAX6106EUR-T pinout, MAX6106EUR-T application, or MAX6106EUR-T equivalent, this device offers verified low-noise (25µVRMS, 10Hz–10kHz), no-output-capacitor-required stability, and dropout as low as 50mV at 1mA - critical for low-voltage, space-constrained, high-accuracy analog signal chains.
Technical Context
The MAX6106EUR-T uses a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve its 75ppm/°C max temperature coefficient and ±0.4% initial accuracy over –40°C to +85°C. Its series-mode architecture eliminates external bias resistors and enables supply current virtually independent of VIN (4–8µA/V variation).
Internally compensated and stable with any capacitive load when sourcing <200µA, it requires no output capacitor for stability - unlike shunt-mode references. Dropout voltage remains ≤200mV across full load range (0–5mA source / –2mA sink) and temperature, enabling operation from single-cell Li-ion or 3.3V rails.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3020AIDBZR | 2.048V, ±0.2% initial accuracy, 50ppm/°C, 50µA IQ, SOT23-3 | Lower drift and IQ but lower output current (25mA max sink/source); less robust under heavy capacitive loads | Select for ultra-low-drift, ultra-low-power systems where load current ≤1mA and board space allows optional 1µF output cap |
| ADR3420ARJZ-R7 | 2.048V, ±0.1% initial accuracy, 30ppm/°C, 120µA IQ, SOT23-3 | Higher accuracy and lower tempco, but requires 1µF output capacitor for stability and has higher quiescent current | Select when absolute initial accuracy and long-term stability outweigh board area constraints and power budget limits |
Compared with REF3020AIDBZR and ADR3420ARJZ-R7, the MAX6106EUR-T trades minor initial accuracy for guaranteed no-capacitor operation, higher output drive (5mA/2mA), and superior supply-voltage independence - making it optimal for cost-sensitive, space-constrained, moderate-accuracy industrial and portable designs.

FAQ
What is the output voltage tolerance and temperature coefficient of the MAX6106EUR-T?
The MAX6106EUR-T provides a nominal 2.048V output with ±0.4% initial accuracy at +25°C and a maximum temperature coefficient of 75ppm/°C over –40°C to +85°C. These specifications are production-tested and guaranteed per Maxim's datasheet revision 3 (2002), ensuring predictable drift behavior in industrial and portable environments where thermal stability is critical.
Does the MAX6106EUR-T require an external output capacitor for stability?
No, the MAX6106EUR-T is internally compensated and does not require an external output capacitor for stability - even with capacitive loads - when sourcing less than 200µA. This eliminates board area and BOM cost, making it ideal for ultra-compact designs like wearable sensors and handheld test equipment where space is constrained.
What is the minimum input voltage needed for the MAX6106EUR-T to regulate properly?
The MAX6106EUR-T requires a minimum input voltage of 2.5V to maintain regulation. Its dropout voltage is specified at 50mV (max) at 1mA load, meaning it can deliver a stable 2.048V output from as low as 2.1V input under light load - supporting operation from deeply discharged single-cell Li-ion batteries down to 2.1V.
Can the MAX6106EUR-T both source and sink current, and what are the limits?
Yes, the MAX6106EUR-T can source up to 5mA and sink up to 2mA of load current. This bidirectional capability allows it to drive reference inputs of multiple ADCs, bias op-amp networks, or interface with active load circuits - eliminating the need for external buffer amplifiers in many precision analog signal chains.
How does the supply current of the MAX6106EUR-T vary with input voltage?
The MAX6106EUR-T draws 90µA typical quiescent current, with variation limited to 4–8µA per volt of input voltage (IIN/VIN). This near-constant supply current - unlike shunt-mode references - ensures predictable power consumption across its 2.5V–12.6V input range, simplifying battery-life estimation in portable systems.
