Product details
Overview
The MAX6050BEUR+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 over –40°C to +85°C, 100mV dropout at 500μA load, and 35μA max quiescent current - enabling high-accuracy ADC/DAC biasing in battery-powered industrial sensors.
For engineers reviewing the MAX6050BEUR+T datasheet, MAX6050BEUR+T pinout, MAX6050BEUR+T application, or MAX6050BEUR+T equivalent, this page delivers verified electrical specs, SOT23-3 terminal mapping, real-world use cases in data acquisition and process control, and two validated alternative parts with documented functional trade-offs.
Technical Context
This device uses a curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <20ppm/°C TC and <0.2% initial error. Its series-mode architecture eliminates external bias resistors and compensation capacitors while supporting bidirectional 500μA load current.
Supply current remains stable across input voltage (0.8μA/V variation), and output remains stable with 0–2.2nF capacitive loading - critical for space-constrained, low-noise analog front-ends where board area and transient response are design constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.2% at +25°C - enables direct 12-bit ADC full-scale calibration without trimming |
| Temp Coefficient | ≤15ppm/°C (0°C to +70°C) - ensures ≤0.75mV drift over industrial temperature range |
| Quiescent Current | ≤35μA - supports >10-year battery life in 10μA sleep-cycle sensor nodes |
| Dropout Voltage | 100mV at 500μA load - allows operation from 5.1V supply in 5V systems with margin |
| Load Regulation | 0.17μV/μA sourcing - maintains <85μV error across full 500μA load swing |
| Line Regulation | 25μV/V - limits output shift to <125μV over 5.0V ±2.5V input variation |
| Capacitive Load Stability | 0–2.2nF - permits direct connection to ADC sample capacitors without oscillation |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Input | Accepts 5.2V to 12.6V; internal regulation rejects ripple up to 72dB at 120Hz |
| 2 (OUT) | Reference Output | 5.000V precision node; sinks/sources ±500μA; stable with no external capacitor |
| 3 (GND) | Analog Ground | Low-impedance return path; must be star-connected to minimize ground bounce in mixed-signal layouts |

FAQ
What is the maximum load current the MAX6050BEUR+T can source or sink?
The MAX6050BEUR+T can source or sink up to ±500μA while maintaining specified accuracy and stability. This bidirectional capability supports both active pull-up and pull-down configurations in precision analog circuits, such as driving ADC reference inputs or biasing op-amp feedback networks. Exceeding ±500μA may increase dropout voltage beyond 200mV and degrade output regulation.
Does the MAX6050BEUR+T require an external output capacitor for stability?
No, the MAX6050BEUR+T is internally compensated and stable with 0–2.2nF output capacitance - including no capacitor. Unlike many references, it does not require external compensation, simplifying layout and saving board space. An optional capacitor may improve transient response under step-load conditions but is never mandatory for stability.
What is the minimum input voltage required for the MAX6050BEUR+T to regulate at 5.000V?
The MAX6050BEUR+T requires a minimum input voltage of VOUT + 200mV = 5.2V to maintain regulation at full 500μA load. At lighter loads, dropout decreases - e.g., 100mV at 500μA - but the absolute minimum VIN is 5.2V across the full operating temperature range (–40°C to +85°C) per datasheet specifications.
How does the MAX6050BEUR+T compare to shunt-mode references in terms of supply efficiency?
Unlike shunt-mode references that waste current through a series resistor, the MAX6050BEUR+T draws only 35μA quiescent current independent of load - with just 0.8μA/V variation over input voltage. This eliminates wasted bias current, improves battery life, and removes the need to size resistors for worst-case load, making it significantly more efficient in variable-load or low-duty-cycle systems.
Is the MAX6050BEUR+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 drop-in replacement across output voltages (1.247V to 5.000V) without PCB redesign - provided input voltage and load requirements are verified for the selected variant.
