Product details
Overview
MAX6067AEUR-T from Maxim Integrated is a precision, low-dropout, micropower 4.5V voltage reference in a 3-pin SOT23 package. It delivers ±0.2% initial accuracy, 20ppm/°C max temperature coefficient, and supports 5mA sourcing / 2mA sinking over –40°C to +85°C. It enables high-accuracy ADC biasing and battery-powered instrumentation where supply current (<125µA) and dropout (<200mV at 1mA) are critical.
For engineers reviewing the MAX6067AEUR-T datasheet, MAX6067AEUR-T pinout, MAX6067AEUR-T application, or MAX6067AEUR-T equivalent, this page provides verified electrical parameters, SOT23-3 terminal roles, real-world load regulation behavior (0.5–0.9 mV/mA), noise performance (55µVp-p, 0.1Hz–10Hz), and validated alternatives for 4.5V reference design.
Technical Context
The MAX6067AEUR-T is a series-mode (three-terminal) voltage reference using proprietary curvature-correction circuitry and laser-trimmed thin-film resistors. Its internal compensation eliminates need for external capacitors, and its supply current varies only 3.2–8.0 µA/V across input voltage range.
It operates with input voltage as low as (VOUT + 0.2V) = 4.7V up to 12.6V, maintains output stability under capacitive loads, and achieves 230µs turn-on settling to 0.1% with 50pF load capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.500V ±0.2% (max) at +25°C - ensures direct compatibility with 4.5V ADC reference inputs without calibration. |
| Temperature Coefficient | 20ppm/°C (max) - guarantees ≤±0.9mV drift over –40°C to +85°C ambient, critical for portable sensor systems. |
| Dropout Voltage | 50–200mV at 1mA load - enables operation from single Li-ion cell (nominal 3.7V) when paired with LDO pre-regulation. |
| Quiescent Supply Current | 90µA (typ), ≤125µA (max) - extends battery life in always-on monitoring devices beyond 10 years at 10µA system sleep current. |
| Load Regulation | 0.5–0.9 mV/mA (source), 2.4–8.0 mV/mA (sink) - defines output shift under dynamic load steps in precision data acquisition. |
| Noise (0.1Hz–10Hz) | 55µVp-p - limits quantization uncertainty to <0.01 LSB in 16-bit 4.5V full-scale ADC conversions. |
| Power Supply Rejection | 70dB at 120Hz - suppresses ripple from switching regulators feeding the reference input. |
Pinout & Package
MAX6067AEUR-T is housed in a RoHS-compliant 3-pin SOT23-3 package (JEDEC MO-178AA), 2.9mm × 1.6mm × 1.1mm, with gull-wing leads and thermal pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply terminal | Accepts 4.7V to 12.6V; requires no series resistor; supplies internal bandgap core and output buffer. |
| 2 (OUT) | Precision reference output | Delivers stable 4.5V; capable of sourcing 5mA or sinking 2mA; stable with ≥0.1µF capacitive loads. |
| 3 (GND) | Analog ground reference | Must be tied to clean system AGND plane; separates reference return from digital or power return paths. |
Key Features
| Feature | Design Value |
|---|---|
| No external capacitor required | Internally compensated architecture eliminates need for output stabilization capacitor-saves PCB area in space-constrained wearables and IoT nodes. |
| Supply-current independence | Only 3.2–8.0 µA/V variation across 4.7–12.6V input range-enables consistent battery drain estimation in wide-input-voltage systems. |
| Low dropout at full load | 200mV max dropout at 1mA ensures usable headroom even with aging batteries or high-impedance supply traces. |
| Stable with capacitive loads | Operates reliably with 0.1µF–1µF output capacitance-supports filtering for noisy environments without oscillation risk. |
| High-output-current capability | 5mA source / 2mA sink drives multiple ADC references or op-amp bias networks without external buffers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF43GM | 4.096V output, 12ppm/°C TC, 100µA IQ, SO-8 package | Requires PCB redesign for 8-pin SOIC; better TC but incompatible voltage for 4.5V ADC full-scale use. | Select only if system uses 4.096V-aligned 12-/16-bit ADCs and board layout allows SOIC footprint. |
| ADR3445 | 4.5V output, 10ppm/°C TC, 120µA IQ, SOT23-3 package | Lower TC and same voltage, but 230µs turn-on time vs. MAX6067AEUR-T's 230µs (identical); 75dB PSRR vs. 70dB. | Prefer ADR3445 for ultra-stable lab instruments; retain MAX6067AEUR-T for cost-sensitive, high-volume portable designs. |
Compared with REF43GM and ADR3445, MAX6067AEUR-T offers optimal balance of 4.5V output alignment, SOT23-3 footprint, and production-proven 20ppm/°C TC-making it the preferred choice for volume portable instrumentation where voltage match and board area are primary constraints.

FAQ
What is the maximum input voltage rating for MAX6067AEUR-T?
The absolute maximum input voltage for MAX6067AEUR-T is +13.5V referenced to GND. However, the guaranteed operating range is 4.7V (VOUT + 0.2V) to 12.6V. Exceeding 12.6V may degrade long-term stability or accelerate parametric drift, so MAX6067AEUR-T should be used within its specified 4.7–12.6V functional window for production reliability.
Does MAX6067AEUR-T require an output capacitor for stability?
No, MAX6067AEUR-T does not require an output capacitor for stability due to internal compensation. It remains stable with capacitive loads from 0 to ≥1µF. An optional 0.1µF ceramic capacitor may be added to improve transient response during large load steps, but omission saves board area-confirmed in the datasheet's Applications Information section.
What is the load current capability of MAX6067AEUR-T?
MAX6067AEUR-T can continuously source up to 5mA and sink up to 2mA while maintaining output accuracy within specifications. Load regulation is characterized at 0.5–0.9 mV/mA (source) and 2.4–8.0 mV/mA (sink), meaning output voltage shifts predictably under load-enabling accurate error budgeting in multi-load reference distribution networks.
How does the temperature coefficient of MAX6067AEUR-T affect system accuracy?
With a max temperature coefficient of 20ppm/°C, MAX6067AEUR-T contributes ≤±0.9mV total drift over –40°C to +85°C (125°C span). For a 4.5V reference, this equals ±0.02% full-scale error-well within requirements for 12-bit (0.024%) and 14-bit (0.006%) systems, making MAX6067AEUR-T suitable for uncalibrated industrial sensors.
Is MAX6067AEUR-T pin-compatible with other devices in the MAX6061–MAX6068 family?
Yes, all MAX6061–MAX6068 variants-including MAX6067AEUR-T-share identical SOT23-3 pinout (IN, OUT, GND) and package dimensions. This allows drop-in replacement across output voltages (1.25V to 5.0V) without PCB revision, provided input voltage and load requirements remain compatible with the new voltage option.
