Product details
Overview
MAX6001EUR-T from Analog Devices is a micropower, low-dropout, series-connected 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 of ADCs, sensors, or precision comparators.
For engineers reviewing the MAX6001EUR-T datasheet, MAX6001EUR-T pinout, MAX6001EUR-T application, or MAX6001EUR-T equivalent, this page delivers verified electrical parameters, validated SOT23-3 terminal mapping, real-world use cases in portable instrumentation and sensor signal chains, and two confirmed alternative references with documented functional trade-offs.
Technical Context
The MAX6001EUR-T implements a bandgap-based series voltage reference architecture with internal compensation, eliminating external capacitors across its full 0–2.2nF load capacitance range. It operates as a three-terminal active regulator (IN, OUT, GND), sourcing or sinking up to ±400µA while maintaining <0.2% output deviation over input voltages from (VOUT + 200mV) to 12.6V.
Its supply current remains stable across VIN (0.8µA/V variation), enabling predictable power budgeting in wide-input-range 3V/5V battery systems. Turn-on settling time is 30µs to 0.1% final value at 25°C with 50pF load, and it exhibits 86dB ripple rejection at 120Hz - critical for noise-sensitive analog front-ends.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3012IDBZT | 1.2V output, 50ppm/°C TC, 50µA max IQ, SOT23-3 - tighter initial accuracy (±0.5%) but higher tempco drift above 60°C | Better for room-temperature lab instruments; less robust over full industrial temperature range | Select when absolute initial accuracy outweighs wide-temp stability |
| ADR3412ARJZ-R7 | 1.2V output, 30ppm/°C TC, 120µA max IQ, SOT23-3 - lower tempco but 2.7× higher quiescent current | Suitable for mains-powered systems where power is not constrained | Choose when ultra-low drift is mandatory and battery life is secondary |
Compared with REF3012IDBZT and ADR3412ARJZ-R7, the MAX6001EUR-T offers the lowest quiescent current among 1.2V SOT23-3 references while maintaining adequate tempco for portable industrial use - making it optimal for cost-sensitive, battery-limited designs needing balanced performance.

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), i.e., 1.45V, to maintain regulation. Below this, output voltage drops nonlinearly. At 400µA load, dropout is specified at 100mV - meaning 1.35V input sustains 1.250V output within tolerance. This enables use with partially discharged single-cell batteries.
Can the MAX6001EUR-T drive a 1000pF capacitive load without oscillation?
Yes, the MAX6001EUR-T is internally compensated and stable with capacitive loads from 0 to 2.2nF - including 1000pF. No external compensation capacitor is needed, unlike many older references. This eliminates layout sensitivity and improves reliability in high-density PCBs where stray capacitance is unavoidable.
Does the MAX6001EUR-T support both sourcing and sinking current at its output?
Yes, the MAX6001EUR-T can source up to +400µA and sink down to –400µA while maintaining output voltage accuracy within specification. This bidirectional capability allows direct interfacing with op-amp inputs, ADC reference pins, or comparator thresholds without additional level-shifting circuitry.
How does the supply current of the MAX6001EUR-T vary with temperature?
The MAX6001EUR-T exhibits minimal temperature dependence in quiescent current: typical values range from 27µA at –40°C to 45µA at +85°C, with 35µA at +25°C. This flat thermal profile simplifies power budgeting in environments with wide ambient swings, such as automotive cabin modules or outdoor sensor nodes.
Is the MAX6001EUR-T pin-compatible with other devices in the MAX6001–MAX6005 family?
Yes, all members of the MAX6001–MAX6005 family share identical SOT23-3 pinout (IN, OUT, GND) and package dimensions. The MAX6001EUR-T can be substituted with MAX6002EUR-T through MAX6005EUR-T on the same footprint - only the output voltage changes (1.25V, 2.5V, 3.0V, 4.096V, 5.0V), enabling flexible design reuse.
