Product details
Overview
MAX6030AEUR+T from Analog Devices is a precision 3.000V series-mode voltage reference in SOT23-3 package, featuring 0.2% initial accuracy, <15ppm/°C temperature coefficient, and 100mV dropout at 500μA load current. It operates from (VOUT + 200mV) to 12.6V supply, draws ≤35μA quiescent current, and supports ±500μA sourcing/sinking-ideal for battery-powered data acquisition and industrial sensor signal conditioning.
For engineers reviewing the MAX6030AEUR+T datasheet, MAX6030AEUR+T pinout, MAX6030AEUR+T application, or MAX6030AEUR+T equivalent, this page delivers verified specifications, SOT23-3 terminal mapping, real-world use cases in low-power analog systems, and two validated alternative parts with documented functional trade-offs.
Technical Context
The MAX6030AEUR+T implements a curvature-corrected bandgap core with laser-trimmed thin-film resistors, enabling <20ppm/°C TC over –40°C to +85°C and 0.2% output voltage accuracy at +25°C. Its series-mode architecture eliminates external biasing resistors and compensation capacitors.
It achieves stable operation with 0–2.2nF load capacitance, exhibits 0.14μV/μA load regulation (sourcing), 20μV/V line regulation, and 80dB ripple rejection at 120Hz-making it suitable for high-resolution ADC references and precision DAC biasing where supply and load transients must not perturb reference stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.2% at +25°C - ensures accurate scaling for 12-bit+ ADCs without calibration |
| Temp Coefficient | <15ppm/°C (max, –40°C to +85°C) - limits drift to <±0.36mV over full range |
| Quiescent Current | ≤35μA - enables >1-year battery life in 10μA-sleep IoT nodes |
| Dropout Voltage | 100mV at 500μA load - allows operation from 3.1V supply in 3.3V systems |
| Load Regulation | 0.14μV/μA (sourcing) - maintains <70μV error across full 500μA load swing |
| Capacitive Load | Stable with 0–2.2nF - eliminates need for output capacitor in space-constrained PCBs |
| Supply Range | 3.2V to 12.6V - compatible with single-cell Li-ion, 3.3V, and 5V rails |
Pinout & Package
SOT23-3 package: 1.12mm × 1.35mm × 1.00mm body, gull-wing leads, RoHS-compliant, JEDEC MO-178AA compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Input | Accepts input from 3.2V–12.6V rail; internal series regulator requires ≥200mV headroom above VOUT |
| 2 (OUT) | Reference Output | Provides stable 3.000V ±0.2%; sinks or sources up to ±500μA with minimal regulation error |
| 3 (GND) | Analog Ground | Low-impedance return path; must be connected directly to system AGND plane to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Proprietary curvature correction | Reduces TC to <15ppm/°C vs. typical 50ppm/°C uncorrected bandgaps |
| Laser-trimmed thin-film resistors | Enables 0.2% initial accuracy without post-package trimming |
| No external compensation required | Eliminates 1–10nF capacitor, saving >0.5mm² board area per device |
| Supply-current independence | Variation only 0.8μA/V - avoids supply-rail dependency seen in shunt references |
| Ultra-low dropout | 100mV at full 500μA load - supports operation in sub-3.3V battery systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3030AIDBVR | 3.0V output, 0.2% initial accuracy, 100ppm/°C TC, 50μA IQ, SOT23-5 package | Higher TC and quiescent current; requires external decoupling capacitor for stability | Select when cost sensitivity outweighs TC and power requirements; verify layout for 100nF bypass |
| ADR3430ARJZ-R7 | 3.0V output, 0.1% initial accuracy, 10ppm/°C TC, 120μA IQ, SOT23-5 package | Lower TC and higher accuracy but 3.4× higher supply current; larger footprint | Choose for metrology-grade stability where battery life is secondary to long-term drift performance |
Compared with REF3030AIDBVR and ADR3430ARJZ-R7, the MAX6030AEUR+T delivers superior TC and lower IQ in a smaller 3-pin SOT23-3 footprint-making it optimal for space- and power-constrained portable instrumentation where 0.2% accuracy suffices.

FAQ
What is the maximum load current the MAX6030AEUR+T can source or sink?
The MAX6030AEUR+T can source or sink up to ±500μA while maintaining specified accuracy and regulation. At 500μA load, dropout voltage remains ≤200mV, and load regulation is 0.14μV/μA (sourcing) or 0.18μV/μA (sinking). Exceeding this current may cause output deviation beyond the 0.2% initial accuracy spec and increased thermal drift.
Does the MAX6030AEUR+T require an external output capacitor for stability?
No, the MAX6030AEUR+T is internally compensated and stable with 0–2.2nF load capacitance. An external capacitor is optional and only recommended in applications with fast load transients (e.g., pulsed ADC sampling) to reduce overshoot. Omitting it saves PCB area and simplifies design-confirmed by Analog Devices' Electrical Characteristics table and Applications Information section.
What is the minimum input voltage required for the MAX6030AEUR+T to regulate properly?
The minimum input voltage for the MAX6030AEUR+T is VOUT + 200mV = 3.2V. Below this, regulation degrades: dropout voltage increases nonlinearly, and output accuracy falls outside the 0.2% specification. The device remains functional down to 2.5V but does not guarantee performance-per the "Supply Voltage Range" specification in the MAX6030 Electrical Characteristics table.
How does the MAX6030AEUR+T compare to shunt voltage references in terms of supply efficiency?
Unlike shunt references that waste current through a series resistor, the MAX6030AEUR+T draws only ≤35μA quiescent current independent of supply voltage (0.8μA/V variation). This eliminates wasted bias current, especially critical in battery systems where shunt references draw ≥100μA even at zero load. The series architecture also avoids resistor tolerance errors and thermal drift from bias components.
Is the MAX6030AEUR+T pin-compatible with other devices in the MAX60xx family?
Yes, all MAX60xx devices-including MAX6012, MAX6021, MAX6025, MAX6030, MAX6041, MAX6045, and MAX6050-share identical SOT23-3 pinout (IN, OUT, GND) and package dimensions. This allows direct substitution across output voltages (1.247V to 5.000V) without PCB redesign, provided supply voltage and load requirements are verified per each part's datasheet.
