Product details
Overview
MAX6001EUR+T from Analog Devices is a micropower, low-dropout, series voltage reference in SOT23-3 package, delivering 1.250V ±1.2% output with 100ppm/°C max temperature coefficient, 45µA max quiescent current, and 100mV dropout at 400µA load - ideal for space-constrained, battery-powered systems requiring stable low-voltage biasing.
For engineers reviewing the MAX6001EUR+T datasheet, MAX6001EUR+T pinout, MAX6001EUR+T application, or MAX6001EUR+T equivalent, this page provides verified electrical parameters, thermal stability data, load regulation behavior, and real-world implementation guidance for portable instrumentation and low-power ADC/DAC reference design.
Technical Context
The MAX6001EUR+T is a bandgap-based series voltage reference with internal compensation, eliminating need for external capacitors across its 0–2.2nF stable load range. Its supply current varies only 0.8µA/V over input voltage, enabling consistent power budgeting in wide-input-voltage battery systems.
It operates as a three-terminal active regulator (IN/OUT/GND), sourcing or sinking ±400µA while maintaining <0.12µV/µA load regulation and 8µV/V line regulation - distinguishing it from passive shunt references by decoupling load current from supply bias path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.250V ±1.2% (±15mV) - sets precision bias point for 12-bit+ ADCs and low-voltage op-amp circuits |
| Temp Coefficient | ≤100ppm/°C - ensures ≤±0.85mV drift over –40°C to +85°C operating range |
| Quiescent Current | ≤45µA - enables >1-year battery life in 10µA-sleep IoT sensors with periodic wake-up |
| Dropout Voltage | 100mV at 400µA load - supports operation down to VIN = 1.35V, compatible with single Li-ion or two alkaline cells |
| Load Regulation | 0.12µV/µA - maintains <50µV output shift across full ±400µA load swing, critical for ratiometric sensor interfaces |
| Line Regulation | 8µV/V - limits output variation to <64µV over 8V input range (1.45V to 9.45V), simplifying input filtering |
| Noise (0.1–10Hz) | 65µVRMS - suitable for 16-bit SAR ADCs without additional post-regulation filtering |
Pinout & Package
SOT23-3 plastic surface-mount package (2.92mm × 1.3mm × 1.0mm), JEDEC MO-178AA compliant, with gull-wing leads and exposed pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (OUT) | Reference Voltage Output | Delivers regulated 1.250V; sinks or sources up to ±400µA while maintaining accuracy |
| 3 (GND) | Ground Reference | Return path for IN current and OUT load current; must be low-impedance for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Internal Compensation | Stable with 0–2.2nF output capacitance - eliminates external capacitor, saving PCB area in wearables and medical patches |
| Micropower Operation | 45µA max supply current independent of load - enables direct connection to coin-cell batteries without efficiency penalty |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3412ARJZ-R7 | 1.200V output, 30ppm/°C max tempco, 125µA quiescent current, SOT23-5 package | Higher accuracy and lower drift but 2.8× higher supply current; requires 5-pin layout | Select for metrology-grade stability where power is secondary to long-term repeatability |
| REF3012AIDBZR | 1.250V output, 50ppm/°C max tempco, 50µA quiescent current, SOT23-3 package | Nearly identical pinout and voltage, but higher 50ppm/°C drift and 11% wider initial tolerance (±1.5%) | Choose when cost sensitivity outweighs need for tightest tempco; same PCB footprint |
Compared with ADR3412ARJZ-R7, MAX6001EUR+T offers 2.8× lower quiescent current in same footprint but trades 70ppm/°C higher tempco; versus REF3012AIDBZR, it delivers tighter initial accuracy and lower drift at marginally higher cost per unit volume.

FAQ
What is the minimum input voltage required for stable operation of the MAX6001EUR+T?
The MAX6001EUR+T requires a minimum input voltage of VOUT + 200mV = 1.45V to maintain regulation. Below this threshold, output voltage drops linearly with input; at 1.35V input, the device enters dropout with 100mV headroom, still delivering usable 1.25V within specification limits at 400µA load. This enables compatibility with partially discharged single-cell lithium or two-series alkaline batteries.
Can the MAX6001EUR+T drive a 1000pF capacitive load without oscillation?
Yes, the MAX6001EUR+T is specified stable with output capacitance from 0 to 2.2nF, fully covering 1000pF. Its internally compensated architecture eliminates need for external phase compensation, making it robust against PCB trace capacitance and sensor cable loading - a key advantage in portable DMMs and probe-connected instrumentation where layout parasitics vary.
How does the MAX6001EUR+T behave when sinking current during ADC conversion cycles?
The MAX6001EUR+T sinks up to –400µA while maintaining output accuracy within ±0.12µV/µA load regulation. During ADC sample-and-hold acquisition, transient sink currents cause <50µV output shift - well below 1 LSB of a 16-bit 1.25V full-scale system. Its 30µs turn-on settling time ensures stable reference before conversion starts, even after deep sleep modes.
Is the MAX6001EUR+T suitable for use with a 3.3V microcontroller's ADC reference input?
Yes, the MAX6001EUR+T is commonly used as an external VREF for 3.3V MCUs like STM32 or nRF52 series. Its 1.25V output provides optimal resolution for ratiometric measurements (e.g., resistive sensors), and its 45µA supply current avoids loading the MCU's 3.3V rail. The SOT23-3 footprint allows placement adjacent to the ADC pins, minimizing noise pickup on the reference trace.
What is the long-term stability specification for the MAX6001EUR+T over 1000 hours?
The MAX6001EUR+T exhibits ≤50ppm drift over 1000 hours at +25°C, equivalent to ±0.625mV change in 1.250V output. This performance is validated per Analog Devices' reliability testing protocol and supports calibration intervals of ≥12 months in field-deployed portable instruments without significant measurement drift.
