Product details
Overview
The MAX6102EUR-T from Maxim Integrated is a low-dropout, micropower, three-terminal series-mode voltage reference delivering a precise 2.500V output with ±0.4% initial accuracy and 75ppm/°C max temperature coefficient over –40°C to +85°C. It draws only 90µA quiescent supply current, supports 5mA sourcing and 2mA sinking, and operates with input voltages as low as (VOUT + 200mV) - enabling use in battery-powered precision ADCs, portable instrumentation, and low-voltage sensor signal chains.
For engineers reviewing the MAX6102EUR-T datasheet, MAX6102EUR-T pinout, MAX6102EUR-T application, or MAX6102EUR-T equivalent, this page delivers verified specifications, SOT23-3 terminal mapping, real-world load/line regulation behavior, and validated alternative options for precision analog design.
Technical Context
The MAX6102EUR-T employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve low drift and high initial accuracy. Its series-mode architecture eliminates external biasing resistors and enables supply current virtually independent of input voltage (4–8µA/V variation).
Internally compensated and stable with any capacitive load when sourcing <200µA, it requires no output capacitor for stability - reducing board area in space-constrained systems. Dropout voltage is 50mV at 1mA load, supporting operation near battery end-of-life.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.4% (max initial error), enabling direct interface with 2.5V ADC references and DACs without trimming. |
| Temperature Coefficient | 75ppm/°C (max), ensuring ≤±1.875mV drift over –40°C to +85°C for stable metrology-grade performance. |
| Quiescent Supply Current | 90µA (typ), 125µA (max); ultra-low power ideal for multi-year battery life in IoT sensors and portable DMMs. |
| Dropout Voltage | 50mV at 1mA load, allowing operation from 2.55V input - critical for single-cell Li-ion or alkaline systems. |
| Load Regulation | 0.9mV/mA (max sourcing), 4.0mV/mA (max sinking), minimizing output shift during dynamic sensor excitation or DAC loading. |
| Ripple Rejection | 86dB at 120Hz, suppressing power-supply noise in mixed-signal systems with shared LDO rails. |
| Noise Voltage | 30µVRMS (10Hz–10kHz), suitable for 16-bit+ data acquisition where reference noise dominates SNR. |
Pinout & Package
MAX6102EUR-T is housed in a 3-pin SOT23-3 package (JEDEC MO-178AA), with pin 1 = IN, pin 2 = OUT, pin 3 = GND. The compact 2.92mm × 1.6mm footprint supports high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Voltage Supply | Accepts (VOUT + 200mV) to 12.6V; internal regulation rejects ripple and tolerates transient undershoot during battery discharge. |
| 2 (OUT) | Precision Reference Output | Provides stable 2.500V source/sink node; no external capacitor required for stability with loads <200µA. |
| 3 (GND) | Analog Ground Reference | Must be connected to clean system ground plane; separates reference return from noisy digital or power grounds. |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Stable with any capacitive load when sourcing <200µA - saves PCB area and BOM cost in wearables and handhelds. |
| Supply-current independence | Variation of only 4–8µA/V across 2.7–12.6V input range - eliminates wasted current vs. shunt references. |
| Low dropout at full load | 200mV max dropout at 5mA source current - maintains regulation during peak sensor excitation pulses. |
| Laser-trimmed thin-film resistors | Enables ±0.4% initial accuracy and 75ppm/°C TC without post-package calibration - reduces test time and yield loss. |
| Curvature-corrected bandgap | Minimizes parabolic drift across temperature - critical for uncalibrated industrial temperature transducers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3025AIDBZR | 2.5V output, ±0.2% initial accuracy, 50ppm/°C TC, but 50µA higher quiescent current (140µA typ). | Better accuracy/TC, but higher supply current limits battery life in always-on sensors. | Choose REF3025AIDBZR when absolute initial accuracy outweighs power budget constraints. |
| ADR3425ARJZ-R7 | 2.5V output, ±0.1% initial accuracy, 10ppm/°C TC, but requires 1.5µF output capacitor for stability and has 120µA quiescent current. | Superior drift performance, but added capacitor increases board area and complicates layout in ultra-compact designs. | Choose ADR3425ARJZ-R7 for lab-grade instruments where long-term stability is prioritized over size and simplicity. |
Compared with REF3025AIDBZR and ADR3425ARJZ-R7, the MAX6102EUR-T offers the optimal balance of ultra-low power (90µA), no-output-capacitor operation, and production-ready 75ppm/°C TC - making it the preferred choice for cost-sensitive, space-constrained, battery-operated precision systems.

FAQ
What is the minimum input voltage required for the MAX6102EUR-T to regulate properly?
The MAX6102EUR-T requires an input voltage ≥ (VOUT + 200mV), i.e., ≥2.7V at room temperature. At 1mA load, dropout is 50mV, so regulation is maintained down to 2.55V. This allows reliable operation from partially discharged single-cell Li-ion (2.7–4.2V) or two-alkaline (2.7–3.2V) supplies. The MAX6102EUR-T datasheet specifies this as (VOUT + 0.2V) to 12.6V.
Does the MAX6102EUR-T require an output capacitor for stability?
No - the MAX6102EUR-T is internally compensated and stable with any capacitive load when sourcing less than 200µA. For loads >200µA, stability depends on capacitance value: avoid 0.5nF–50nF ranges. Most applications (e.g., ADC references, op-amp biasing) operate well without an output capacitor, saving board space. The MAX6102EUR-T's no-capacitor capability is explicitly confirmed in its Applications Information section.
What is the load current capability of the MAX6102EUR-T?
The MAX6102EUR-T can source up to 5mA and sink up to 2mA while maintaining specified accuracy. Load regulation is 0.9mV/mA (max) when sourcing and 4.0mV/mA (max) when sinking. This supports driving ADC reference inputs, op-amp feedback networks, and small LED bias circuits directly - eliminating need for external buffers in many designs using the MAX6102EUR-T.
How does the MAX6102EUR-T compare to shunt voltage references in terms of power efficiency?
Unlike shunt references that waste current through a series resistor, the MAX6102EUR-T's series-mode architecture draws only 90µA quiescent current - independent of input voltage (±4–8µA/V variation). Shunt references must be biased for worst-case load, wasting current even at light loads. This makes the MAX6102EUR-T significantly more efficient, especially in battery-powered systems where the MAX6102EUR-T extends operational life by minimizing idle current drain.
Is the MAX6102EUR-T suitable for use in automotive applications?
The MAX6102EUR-T is specified for –40°C to +85°C operation and meets industrial temperature requirements, but it is not AEC-Q200 qualified or rated for automotive under-hood environments (–40°C to +125°C). For automotive cabin or infotainment applications within its temperature range, it may be used with system-level validation. However, for engine control or ADAS systems, AEC-Q100-qualified alternatives should be selected instead of the MAX6102EUR-T.
