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, <20ppm/°C temperature coefficient over –40°C to +85°C, 100mV dropout at 500μA load, and 35μA max quiescent current. It serves as a stable reference for ADCs, DACs, and sensor signal conditioning in battery-powered industrial instrumentation.
For engineers reviewing the MAX6050AEUR+T datasheet, MAX6050AEUR+T pinout, MAX6050AEUR+T application, or MAX6050AEUR+T equivalent, this page delivers verified electrical specifications, SOT23-3 terminal mapping, real-world use cases in low-power analog systems, and validated alternative parts with documented functional trade-offs.
Technical Context
The MAX6050AEUR+T uses a curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <20ppm/°C TC and 0.2% initial tolerance. 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 and maintains stability across input voltages from (VOUT + 0.2V) to 12.6V - enabling direct integration into space-constrained, low-voltage systems where supply headroom is minimal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.2% at +25°C - ensures accurate full-scale calibration for 12-bit+ data converters |
| Temp Coefficient | <20ppm/°C (–40°C to +85°C) - limits drift to ≤1mV over full industrial temperature range |
| Quiescent Current | ≤35μA - enables multi-year operation on coin-cell batteries in portable sensors |
| Dropout Voltage | 100mV at 500μA load - allows operation from 5.1V supply in 5V-rail systems with margin |
| Load Regulation | 0.17μV/μA sourcing - holds output within 85μV error across full 500μA load swing |
| Line Regulation | 25μV/V - rejects supply ripple better than 0.005%/V in noisy DC-DC outputs |
| Capacitive Load Stability | 0–2.2nF - eliminates need for output capacitor, saving PCB area in wearables and IoT nodes |
Pinout & Package
SOT23-3 package (JEDEC TO-236AB), 2.92mm × 1.30mm × 1.00mm body, gull-wing leads, RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (OUT) | Reference Voltage Output | Delivers regulated 5.000V; sinks or sources up to ±500μA with sub-mV regulation error |
| 3 (GND) | Ground Reference | Low-impedance return path; must be connected directly to clean analog ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Series-mode architecture | Eliminates external bias resistor and associated power waste - improves efficiency vs. shunt references |
| Supply-current independence | Only 0.8μA/V variation across input range - simplifies power budgeting in variable-supply systems |
| Internal compensation | Stable with 0–2.2nF load capacitance - removes capacitor footprint and BOM cost in compact designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050IDBZR | 5.0V, 3ppm/°C max TC, 50μA IQ, SOIC-8 package | Higher accuracy and lower TC, but larger footprint and higher current - suited for lab-grade instruments | Select when TC & long-term stability outweigh size/power constraints; not drop-in due to SOIC-8 vs. SOT23-3 |
| ADR3450ARJZ-R7 | 5.0V, 10ppm/°C max TC, 35μA IQ, SOT23-5 (with enable pin) | Includes shutdown control and slightly better TC, but requires routing for EN pin and has different pinout | Choose when system-level power sequencing is required; pinout incompatible with MAX6050AEUR+T PCB layout |
Compared with REF5050IDBZR and ADR3450ARJZ-R7, the MAX6050AEUR+T offers the smallest footprint and lowest supply current among 5V references with ≤0.2% initial accuracy - making it optimal for space- and energy-constrained embedded systems where moderate TC is acceptable.

FAQ
What is the maximum input voltage for the MAX6050AEUR+T?
The MAX6050AEUR+T supports an absolute maximum input voltage of +13.5V, but its specified operating range is (VOUT + 0.2V) to 12.6V - meaning minimum valid input is 5.2V. Operation below 5.2V risks dropout and output regulation loss. The device draws up to 200μA during turn-on if VIN is near minimum.
Does the MAX6050AEUR+T require an external output capacitor?
No, the MAX6050AEUR+T is internally compensated and stable with 0–2.2nF load capacitance. An external capacitor is optional and only beneficial in applications with fast load or supply transients - such as multiplexed sensor arrays - where it reduces overshoot/undershoot. Omitting it saves board area in space-critical designs.
Can the MAX6050AEUR+T sink and source current simultaneously?
No - the MAX6050AEUR+T operates in series mode and can either sink or source up to ±500μA, but not both at once. Its output stage is a single-ended buffer: sourcing occurs when load draws current from OUT to GND; sinking occurs when current flows from IN into OUT. Bidirectional capability refers to polarity of load current, not concurrent operation.
What is the long-term stability specification for the MAX6050AEUR+T?
The MAX6050AEUR+T exhibits 50ppm change in output voltage after 1000 hours of operation at +25°C. This drift is measured under constant bias and represents typical aging behavior; it does not accumulate linearly - most change occurs in the first 1000 hours, with diminishing returns thereafter.
How does the MAX6050AEUR+T compare to shunt references like TL431 in terms of supply efficiency?
Unlike the TL431 - which requires a series resistor and draws constant current regardless of load - the MAX6050AEUR+T draws only 35μA quiescent current independent of load. At zero load, TL431-based designs waste >1mA; the MAX6050AEUR+T cuts that overhead by >95%, directly extending battery life in always-on sensor nodes.
