Product details
Overview
MAX6050BEUR-T from Analog Devices is a precision 5.0V 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 stable reference voltage for high-resolution ADCs and battery-powered instrumentation requiring low quiescent current (35μA max) and minimal board space.
For engineers reviewing the MAX6050BEUR-T datasheet, MAX6050BEUR-T pinout, MAX6050BEUR-T application, or MAX6050BEUR-T equivalent, this page provides verified specifications, real-world application context, pin-level circuit role definitions, and validated alternative options for precision analog signal chains in space-constrained industrial and portable systems.
Technical Context
The MAX6050BEUR-T uses a curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <20ppm/°C TC over –40°C to +85°C and ±0.2% output voltage tolerance at +25°C. Its series-mode architecture eliminates external biasing resistors and supports bidirectional 500μA load current without instability.
Internally compensated for capacitive loads up to 2.2nF, it requires no external capacitor for stability. Supply current varies only 0.8μA/V across 5.2V to 12.6V input range, enabling predictable power budgeting in low-voltage systems where VIN may approach VOUT + 200mV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.2% at +25°C - ensures accurate full-scale calibration for 12–16-bit ADCs without trimming |
| Temp Coefficient | ≤15ppm/°C (0°C to +70°C) - limits drift to ≤0.75mV over industrial temperature range |
| Quiescent Current | ≤35μA - enables >10-year battery life in 10μA-sleep IoT sensors |
| Dropout Voltage | 100mV at 500μA load - allows operation from 5.1V supply in 5V-rail systems |

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 footprint (SOT23-5); not suitable for 2.2nF-capacitance-constrained layouts | Select when ultra-low TC is prioritized over board area and capacitor elimination |
| REF5050AIDBVR | 5.0V output, 3ppm/°C TC, 950μA quiescent current, SOIC-8 package, needs external 10nF compensation | Lower drift but 27× higher supply current; incompatible with battery-operated designs | Select only for lab-grade instrumentation where power is unlimited and drift must be <1ppm/°C |
Compared with ADR3450ARJZ-R7 and REF5050AIDBVR, the MAX6050BEUR-T uniquely balances 0.2% accuracy, 15ppm/°C TC, 35μA supply current, and capacitor-free 2.2nF load stability in SOT23-3-making it optimal for volume production of compact, long-life portable instruments.

FAQ
What is the maximum input voltage rating for the MAX6050BEUR-T?
The MAX6050BEUR-T has an absolute maximum input voltage of +13.5V referenced to GND. However, its specified operating input range is VOUT + 0.2V (5.2V) to 12.6V. Exceeding +13.5V risks permanent damage. For reliable operation, maintain VIN within 5.2V–12.6V and ensure transient spikes remain below +13.5V with appropriate clamping.
Can the MAX6050BEUR-T drive a 1000pF capacitive load without oscillation?
Yes, the MAX6050BEUR-T is guaranteed stable with capacitive loads from 0 to 2.2nF per the datasheet. A 1000pF (1nF) load falls well within this range and requires no external compensation capacitor. This capability simplifies layout in ADC reference buffer circuits and eliminates risk of ringing or overshoot during load transients.
What is the output voltage tolerance of the MAX6050BEUR-T over temperature?
The MAX6050BEUR-T (B-grade) guarantees ±0.4% output voltage tolerance over the full –40°C to +85°C range. At +25°C, it is trimmed to 4.990V–5.010V (±0.2%). The 15ppm/°C max temperature coefficient contributes ≤±0.75mV drift over 0°C to +70°C, ensuring total error remains within design margins for 12-bit systems.
Does the MAX6050BEUR-T require an external resistor for biasing?
No, the MAX6050BEUR-T is a series-mode voltage reference and does not require an external bias resistor. Unlike shunt-mode references, its quiescent current (≤35μA) is internally regulated and virtually independent of input voltage-eliminating wasted current and simplifying design for battery-powered applications.
How does the MAX6050BEUR-T behave during short-circuit conditions?
When the OUT pin is shorted to GND or IN with VIN < 6V, the MAX6050BEUR-T sustains continuous short-circuit current up to 4mA. If VIN ≥ 6V, short-circuit protection limits duration to 60 seconds. This behavior protects the device during board-level testing or fault conditions without requiring external current limiting.
