Product details
Overview
MAX6050AEUR-T from Analog Devices is a precision 5.000V series-mode voltage reference in SOT23-3 package, featuring 0.2% initial accuracy, 15ppm/°C max temperature coefficient, and 100mV dropout at 500μA load current. It delivers ultra-low 35μA quiescent supply current with <0.8μA/V variation across 5.2V–12.6V input range, enabling high-efficiency operation in battery-powered data acquisition and industrial sensor interfaces.
For engineers reviewing the MAX6050AEUR-T datasheet, MAX6050AEUR-T pinout, MAX6050AEUR-T application, or MAX6050AEUR-T equivalent, key selection criteria include its guaranteed 5.000V output (±0.2%), stability with 0–2.2nF capacitive loads, ±500μA sourcing/sinking capability, and compatibility with low-voltage systems requiring minimal power overhead and no external compensation components.
Technical Context
The MAX6050AEUR-T employs a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <20ppm/°C TC over –40°C to +85°C and 50ppm/1000h long-term stability. Its series-mode architecture eliminates dependency on external biasing resistors and enables supply-current independence from VIN.
Internally compensated for capacitive loads up to 2.2nF, it achieves 220μs turn-on settling time to 0.1% with 50pF load and maintains 72dB ripple rejection at 120Hz. Dropout voltage remains ≤200mV across full temperature range at 500μA load, supporting operation from as low as 5.2V input.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3450ARJZ-R7 | 5.0V output, 10ppm/°C TC, 4μA higher quiescent current (39μA), requires 1μF output cap for stability | Higher accuracy but larger board footprint due to required capacitor and larger SOT23-5 package | Select when lower TC outweighs board space and power constraints |
| REF5050AIDBVR | 5.0V output, 3ppm/°C TC, 950μA quiescent current, SOIC-8 package, needs external decoupling | Ultra-low drift for metrology-grade instruments; unsuitable for battery operation due to high supply current | Select only for mains-powered test equipment where ultimate stability justifies power and size penalty |
Compared with ADR3450ARJZ-R7 and REF5050AIDBVR, the MAX6050AEUR-T uniquely balances sub-20ppm/°C drift, 35μA supply current, and capacitor-free operation in the smallest SOT23-3 footprint-making it optimal for portable, low-power, space-constrained precision analog systems.

FAQ
What is the guaranteed output voltage tolerance of the MAX6050AEUR-T over temperature?
The MAX6050AEUR-T guarantees 5.000V ±0.2% initial accuracy at +25°C, with total error including temperature drift limited to ±0.2% over –40°C to +85°C for the 'A' grade. This is achieved via laser trimming and curvature correction, ensuring predictable performance without system-level calibration.
Can the MAX6050AEUR-T operate without an output capacitor?
Yes, the MAX6050AEUR-T is internally compensated and stable with 0–2.2nF output capacitance. No external capacitor is required for stability, reducing BOM count and PCB area-critical for wearables and miniaturized sensors where every mm² matters.
What is the minimum input voltage required for the MAX6050AEUR-T to maintain regulation?
The MAX6050AEUR-T requires a minimum input voltage of VOUT + 200mV = 5.2V to maintain regulation at full 500μA load. At lighter loads, dropout decreases linearly-enabling use with tightly regulated 5.25V supplies in low-noise analog subsystems.
How does the MAX6050AEUR-T compare to shunt voltage references in terms of power efficiency?
Unlike shunt references that waste current through a series resistor, the MAX6050AEUR-T draws only 35μA quiescent current independent of load. This eliminates fixed bias current, cuts power consumption by >50% in intermittent-use applications, and avoids thermal drift from resistor self-heating.
Is the MAX6050AEUR-T pin-compatible with other devices in the MAX6012 family?
Yes, all MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 variants share identical SOT23-3 pinout (IN, OUT, GND) and footprint. Swapping between 1.247V–5.000V versions requires only schematic and BOM updates-no PCB redesign.
