Product details
Overview
MAX6063BEUR+T from Maxim Integrated is a precision, low-dropout, micropower 3.0V series voltage reference in a 3-pin SOT23 package. It delivers ±0.4% initial accuracy, 20ppm/°C max temperature coefficient, and supports 5mA sourcing / 2mA sinking load current. Designed for high-accuracy ADC biasing in portable battery-powered systems, it operates from (VOUT + 0.2V) to 12.6V with only 90µA typical quiescent current.
For engineers reviewing the MAX6063BEUR+T datasheet, MAX6063BEUR+T pinout, MAX6063BEUR+T application, or MAX6063BEUR+T equivalent, key selection criteria include its 3.0V output tolerance, ultra-low supply current independence from input voltage, dropout voltage ≤200mV at 1mA, absence of required output capacitor, and guaranteed performance across –40°C to +85°C.
Technical Context
The MAX6063BEUR+T is a three-terminal series-mode voltage reference employing proprietary curvature-correction circuitry and laser-trimmed thin-film resistors. Its internal compensation eliminates need for external capacitors, while BiCMOS process enables stable operation with capacitive loads up to 1µF.
It features supply-current variation of only 3.4–8.0µA/V across 2.5V–12.6V input range and maintains output regulation under load currents from –2mA (sink) to +5mA (source), with line regulation as tight as 90µV/V and load regulation of 0.5–6.0mV/mA depending on direction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.4% (2.988V to 3.012V at +25°C) - ensures accurate full-scale reference for 12-bit+ ADCs without calibration. |
| Temp Coefficient | ≤20ppm/°C (max) - limits drift to <±0.5mV over –40°C to +85°C ambient, critical for precision sensor interfaces. |
| Quiescent Current | 90µA (typ), ≤125µA (max) - enables >1-year battery life in coin-cell–powered IoT sensors drawing µA-level average current. |
| Dropout Voltage | ≤200mV at 1mA load - allows operation from 3.2V supply, supporting single-cell Li-ion or dual-cell alkaline systems. |
| Load Current Range | Sources up to 5mA / sinks up to 2mA - drives SAR ADC reference inputs, op-amp bias networks, and small DACs directly. |
| Noise (0.1–10Hz) | 35µVp-p - contributes <0.012 LSB error in 16-bit 3V ADCs, preserving effective resolution. |
| PSRR | 76dB at 120Hz - suppresses ripple from switching regulators feeding the reference, reducing measurement noise. |
Pinout & Package
MAX6063BEUR+T is housed in a standard 3-pin SOT23-3 package (JEDEC MO-178AA), with 1.3mm × 2.9mm footprint and 1.0mm height. Pin 1 is IN, Pin 2 is OUT, Pin 3 is GND - compatible with automated placement and reflow soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply terminal | Accepts 3.2V–12.6V input; requires no series resistor; bypass capacitor (0.1µF) recommended for optimal line-transient rejection. |
| 2 (OUT) | Precision 3.0V reference output | Low-impedance buffered output; stable with 0–1µF capacitive loads; no external compensation capacitor needed. |
| 3 (GND) | Analog ground reference | Must be connected to clean system analog ground plane; separate from digital ground if mixed-signal layout used. |
Key Features
| Feature | Design Value |
|---|---|
| Initial accuracy | ±0.4% (MAX6063B grade) - reduces system gain error in factory-calibrated instruments without trimming. |
| Temperature stability | 20ppm/°C max - enables uncalibrated operation in industrial temperature ranges without thermal compensation circuits. |
| No output capacitor required | Fully internally compensated - saves PCB area and BOM cost in space-constrained wearables and medical patches. |
| Supply current independence | Only 3.4–8.0µA/V variation - eliminates input-voltage–dependent error in battery-monitoring applications with decaying supply. |
| Low dropout | 200mV max at 1mA - permits direct regulation from low-headroom sources like LDO outputs or partially discharged batteries. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3030AIDBZR | 3.0V, ±0.2% initial accuracy, 50ppm/°C max tempco, 50µA IQ, SOT23-3 | Higher accuracy but worse temperature stability; lower IQ benefits ultra-low-power sleep modes | Select REF3030AIDBZR when long-term stability at room temperature outweighs wide-temperature performance. |
| ADR3430ARJZ-R7 | 3.0V, ±0.1% initial accuracy, 10ppm/°C max tempco, 120µA IQ, SOT23-3 | Better tempco and accuracy, but higher quiescent current and tighter input voltage range (3.3V–15V) | Select ADR3430ARJZ-R7 for lab-grade instrumentation where 10ppm/°C stability justifies 33% higher supply current. |
Compared with REF3030AIDBZR and ADR3430ARJZ-R7, MAX6063BEUR+T offers the best balance of low dropout (≤200mV), ultra-low supply-current variation (<8µA/V), and robust capacitive-load stability-making it optimal for battery-operated systems with variable input voltage and space constraints.

FAQ
What is the maximum input voltage rating for MAX6063BEUR+T?
The absolute maximum input voltage for MAX6063BEUR+T is +13.5V referenced to GND. However, the specified operating range is (VOUT + 0.2V) to 12.6V - i.e., 3.2V to 12.6V - with guaranteed line regulation and thermal performance across –40°C to +85°C. Exceeding 12.6V may degrade long-term stability or violate safe operating area limits.
Does MAX6063BEUR+T require an output capacitor for stability?
No, MAX6063BEUR+T is internally compensated and does not require an output capacitor for stability - a key differentiator from many competing references. An optional 0.1µF ceramic capacitor may be added to improve transient response under large load steps, but it is never mandatory for oscillation prevention or DC regulation.
What is the load current capability of MAX6063BEUR+T?
MAX6063BEUR+T can source up to 5mA into a load and sink up to 2mA from a load while maintaining output voltage within specification. This bidirectional capability supports both active-high and active-low reference configurations, such as driving ADC reference inputs or biasing op-amp feedback networks.
How does the temperature coefficient of MAX6063BEUR+T compare to other 3V references?
MAX6063BEUR+T has a maximum temperature coefficient of 20ppm/°C - matching top-tier performance in its class. This is significantly better than general-purpose references (e.g., LM385: 100ppm/°C) and competitive with premium alternatives like ADR3430 (10ppm/°C), while offering lower dropout and superior supply-current stability.
Is MAX6063BEUR+T pin-compatible with other parts in the MAX6061–MAX6068 family?
Yes, all MAX6061–MAX6068 variants, including MAX6063BEUR+T, share identical 3-pin SOT23-3 pinout (IN, OUT, GND) and mechanical footprint. This allows drop-in replacement across output voltages (1.25V–5.0V) without PCB redesign - provided input voltage and load requirements remain compatible.
