Product details
Overview
The MAX6010AEUR+T from Maxim Integrated is a precision 3V series voltage reference IC in a 3-pin SOT23 package, delivering ±0.2% initial accuracy, 50ppm/°C max temperature drift, and ultra-low 5µA (max) supply current. It operates from 3.2V to 5.5V input, provides 200mV dropout at 1mA, and supports 7mA sourcing for high-accuracy analog signal conditioning in portable instrumentation.
For engineers reviewing the MAX6010AEUR+T datasheet, MAX6010AEUR+T pinout, MAX6010AEUR+T application, or MAX6010AEUR+T equivalent, key selection criteria include micropower operation under varying input voltage, load regulation performance up to 7mA, low-noise output stability with 1nF–1µF capacitive loads, and guaranteed performance across –40°C to +85°C.
Technical Context
The MAX6010AEUR+T is a bandgap-based, three-terminal series voltage reference optimized for low-dropout operation and minimal supply current variation. Its internal architecture eliminates external resistor dependency and maintains <0.05µA/V supply current sensitivity across 3.2V–5.5V input range.
It achieves stable 3V output with 200µV/mA (max) load regulation when sourcing up to 7mA and 350µV/V (max) line regulation over full input range-enabling use in battery-powered systems where supply voltage sags during discharge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.2% (±6mV) at +25°C - ensures ADC/DAC reference accuracy within 12-bit resolution limits |
| Initial Accuracy | ±0.2% (Grade A) - guarantees absolute output tolerance without calibration in production |
| Temp Drift | 50ppm/°C max - contributes ≤1.5mV error over –40°C to +85°C operating range |
| Dropout Voltage | 200mV max at 1mA - enables operation down to 3.2V input, critical for single-cell Li-ion or alkaline systems |
| Supply Current | 5µA max - extends battery life beyond 10 years in 10µA-system standby applications |
| Noise (0.1–10Hz) | 100µVP-P - minimizes quantization uncertainty in high-resolution data acquisition |

Pinout & Package
MAX6010AEUR+T uses a RoHS-compliant 3-pin SOT23 package (package code U3-1), with 1.3mm × 0.8mm footprint and 0.95mm height. Pin 1 = IN (supply input), Pin 2 = OUT (3V reference output), Pin 3 = GND (ground reference).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Voltage Input | Accepts 3.2V–5.5V DC; requires ≥0.1µF bypass capacitor to ground for PSRR optimization |
| 2 (OUT) | Reference Voltage Output | Delivers stable 3V; must be bypassed with 1nF–1µF capacitor to ground for stability and transient response |
| 3 (GND) | Ground Reference | Low-impedance return path; connects directly to system analog ground plane to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 5µA max with <0.05µA/V variation - eliminates need for shutdown control in always-on sensing nodes |
| Capacitive-load stability | Stable with 1nF to 1µF output capacitance - simplifies layout in space-constrained PCBs without compensation networks |
| Low dropout operation | 200mV at 1mA - enables direct regulation from partially discharged batteries without intermediate LDO |
| Low thermal hysteresis | 210ppm - preserves calibration integrity after repeated thermal cycling in industrial environments |
| High PSRR | 50dB at ≤2kHz - rejects ripple from switching regulators feeding mixed-signal subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3030AIDBZR | 3V output, ±0.2% initial accuracy, 50ppm/°C drift, but 50µA quiescent current - 10× higher than MAX6010AEUR+T | Suitable for higher-current systems where power budget allows; not viable for sub-10µA standby designs | Select REF3030AIDBZR only if board-level filtering or higher PSRR (>60dB) is required - MAX6010AEUR+T offers superior micropower trade-off |
| ADR3430ARJZ-R7 | 3V output, ±0.1% initial accuracy, 30ppm/°C drift, 6µA supply current - tighter accuracy but higher cost and same power class | Better for metrology-grade calibration; less optimal for cost-sensitive portable equipment | Choose ADR3430ARJZ-R7 when 0.1% absolute accuracy is mandatory; MAX6010AEUR+T delivers best value for 0.2% industrial grade |
Compared with REF3030AIDBZR and ADR3430ARJZ-R7, the MAX6010AEUR+T uniquely balances ultra-low 5µA supply current, 0.2% accuracy, and SOT23 footprint - making it the preferred choice for battery longevity-critical applications where moderate accuracy suffices.

FAQ
What is the maximum load current the MAX6010AEUR+T can source while maintaining specified accuracy?
The MAX6010AEUR+T can source up to 7mA while maintaining its specified load regulation of 200µV/mA (max). At 7mA, output voltage deviation remains within ±1.4mV of nominal 3.000V, preserving accuracy for precision ADC references and sensor excitation circuits. This capability is validated across –40°C to +85°C and does not require external current-boosting circuitry. The MAX6010AEUR+T achieves this with only 200mV dropout at 1mA, confirming robust sourcing headroom.
Does the MAX6010AEUR+T require an external resistor for operation?
No, the MAX6010AEUR+T is a three-terminal series voltage reference and does not require an external resistor - unlike shunt-mode references. Its supply current is virtually independent of input voltage (varying only 0.05µA/V), eliminating resistor-related power loss and accuracy degradation. The MAX6010AEUR+T operates with just two external capacitors: ≥0.1µF on IN and 1nF–1µF on OUT. This simplifies design and improves reliability in compact portable systems.
What is the minimum output capacitance required for stability of the MAX6010AEUR+T?
The MAX6010AEUR+T requires a minimum output capacitance of 1nF to ensure stability across all operating conditions. It remains stable with output capacitors up to 1µF, enabling flexibility in transient response tuning. This wide capacitive-load range eliminates the need for series resistance or complex compensation networks. The MAX6010AEUR+T's internal design guarantees phase margin >45° across this range, verified in typical operating characteristics plots (toc07, toc13).
How does the MAX6010AEUR+T perform under varying input voltage conditions?
The MAX6010AEUR+T exhibits 350µV/V (max) line regulation from 3.2V to 5.5V input, translating to ≤0.875mV output change over full range. Its supply current varies only 0.05µA/V, ensuring consistent power draw regardless of battery voltage sag. These specifications are guaranteed over –40°C to +85°C. The MAX6010AEUR+T thus maintains reference integrity in systems powered by aging or partially discharged batteries without recalibration.
Is the MAX6010AEUR+T compatible with lead-free PCB assembly processes?
Yes, the MAX6010AEUR+T is supplied in a lead(Pb)-free/RoHS-compliant SOT23 package rated for soldering at +300°C for 10 seconds. Its BiCMOS process and package construction meet JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow profiles. The device has been qualified for industrial temperature operation (–40°C to +85°C) under thermal cycling and humidity exposure per JEDEC standards. MAX6010AEUR+T supports full lead-free manufacturing without derating.
