Product details
Overview
MAX6030BEUR-T from Analog Devices is a precision 3.000V series-mode voltage reference in SOT23-3 package, featuring ±0.4% initial accuracy, <30ppm/°C temperature coefficient over –40°C to +85°C, 35μA max quiescent current, and 100mV dropout at 500μA load-designed for high-accuracy ADC/DAC biasing in battery-powered instrumentation.
For engineers reviewing the MAX6030BEUR-T datasheet, MAX6030BEUR-T pinout, MAX6030BEUR-T application, or MAX6030BEUR-T equivalent, key selection criteria include output stability under varying load (±0.80μV/μA sink/source), supply-voltage-independent current (0.8μA/V variation), and capacitive-load tolerance up to 2.2nF without external compensation.
Technical Context
The MAX6030BEUR-T implements a curvature-corrected bandgap core with laser-trimmed thin-film resistors, enabling low drift and high initial accuracy without external trimming. Its series-mode architecture eliminates the need for bias resistors and supports bidirectional 500μA load current while maintaining regulation across input voltages from 3.2V to 12.6V.
Internally compensated for stability with 0–2.2nF output capacitance, it achieves 100μs typical turn-on settling to 0.1% and delivers 80dB ripple rejection at 120Hz. The device operates reliably across –40°C to +85°C with 130ppm temperature hysteresis and 50ppm/1000h long-term stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.4% at +25°C - ensures precise bias for 12-bit+ data converters without calibration. |
| Temp Coefficient | ≤30ppm/°C (–40°C to +85°C) - limits full-range drift to <900μV, critical for portable metrology. |
| Quiescent Current | ≤35μA - enables >1-year operation on coin-cell batteries in always-on sensor nodes. |
| Dropout Voltage | 100mV at 500μA load - allows use with 3.3V rails down to 3.1V, supporting ultra-low-voltage systems. |
| Load Regulation | ±0.80μV/μA (sink) / ±0.60μV/μA (source) - maintains <0.4mV error across full 500μA load swing. |
| Line Regulation | 20μV/V - holds output stable despite ±10% input rail variation in noisy industrial supplies. |
| Capacitive Load | Stable with 0–2.2nF - eliminates need for external capacitor, saving PCB area in space-constrained wearables. |
Pinout & Package
SOT23-3 surface-mount package (JEDEC TO-236AB), 2.92mm × 1.30mm × 1.02mm body, RoHS-compliant, tape-and-reel packaging for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Input | Accepts 3.2V–12.6V input; internal series regulator draws ≤35μA independent of VIN. |

| 3 (GND) | Ground Reference | Low-impedance return path; must be connected directly to system ground plane for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Proprietary curvature correction | Reduces temperature-induced nonlinearity, enabling <30ppm/°C drift without external circuitry. |
| Laser-trimmed thin-film resistors | Guarantees ±0.4% initial accuracy at +25°C and <130ppm hysteresis after thermal cycling. |
| No external compensation required | Stable with 0–2.2nF load capacitance-eliminates capacitor footprint and BOM cost in compact designs. |
| Supply-current independence | 0.8μA/V VIN variation ensures predictable power budget across wide input ranges (e.g., fading battery). |

FAQ
What is the maximum load current the MAX6030BEUR-T can source and sink?
The MAX6030BEUR-T can source and sink up to ±500μA while maintaining regulation within specifications. This bidirectional capability allows it to drive ADC reference inputs, op-amp bias networks, or sensor excitation circuits without external buffers-critical for minimizing component count in compact designs using the MAX6030BEUR-T.
Does the MAX6030BEUR-T require an external output capacitor for stability?
No, the MAX6030BEUR-T is internally compensated and stable with output capacitance ranging from 0 to 2.2nF. Unlike many references, it does not require an external capacitor for phase margin-enabling capacitor-free layouts in ultra-miniaturized applications such as hearing aids or implantable sensors where every mm² matters for the MAX6030BEUR-T.
What is the minimum input voltage required for the MAX6030BEUR-T to regulate at full load?
The MAX6030BEUR-T requires a minimum input voltage of VOUT + 200mV = 3.2V to maintain regulation at 500μA load current. Its 100mV dropout voltage (typical) ensures reliable operation even as battery voltage declines, extending usable runtime in systems powered by single-cell Li-ion or alkaline sources using the MAX6030BEUR-T.
How does the supply current of the MAX6030BEUR-T vary with input voltage?
The MAX6030BEUR-T exhibits only 0.8μA/V variation in quiescent supply current across its 3.2V–12.6V input range. This near-constant current draw-max 35μA-simplifies power budgeting and avoids efficiency loss seen in shunt references, making the MAX6030BEUR-T ideal for energy-harvesting and battery-backed systems.
Is the MAX6030BEUR-T pin-compatible with other devices in the MAX60xx family?
Yes, all MAX60xx devices-including MAX6030BEUR-T-share identical SOT23-3 pinout (IN, OUT, GND) and package dimensions. This enables direct substitution across output voltages (1.247V to 5.000V) without PCB redesign, streamlining variant management in platforms using multiple MAX60xx references like the MAX6030BEUR-T.
