Product details
Overview
MAX6106EUR from Maxim Integrated is a 2.048V, low-dropout (50mV at 1mA), micropower (90µA typical) series-mode voltage reference in a 3-pin SOT23 package, featuring ±0.4% initial accuracy and 75ppm/°C max temperature coefficient over –40°C to +85°C - used for precision ADC/DAC biasing and battery-powered sensor signal conditioning.
For engineers reviewing the MAX6106EUR datasheet, MAX6106EUR pinout, MAX6106EUR application, or MAX6106EUR equivalent, this page delivers verified technical context, real-world load regulation (0.9mV/mA sourcing), dropout behavior, stability with capacitive loads, and validated alternatives for portable instrumentation and low-voltage embedded systems.
Technical Context
The MAX6106EUR employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve low drift and high initial accuracy. It operates as a three-terminal series-mode reference, eliminating need for external bias resistors or compensation capacitors.
Its supply current remains stable across input voltage (4–8µA/V variation), supports ±2mA sink / +5mA source capability, and maintains stability with any capacitive load when sourcing <200µA - enabling direct integration into space-constrained, battery-operated designs without output capacitor overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048V (±0.4% initial accuracy at +25°C; enables precise 12-bit ADC full-scale reference) |
| Temp Coefficient | 75ppm/°C max (–40°C to +85°C; ensures <±1.5mV drift over full range) |
| Dropout Voltage | 50mV at 1mA load (allows operation from 2.5V supply with 2.048V output; critical for single-cell Li-ion systems) |
| Quiescent Current | 90µA typical (ultra-low power draw extends battery life in always-on sensor nodes) |
| Load Regulation | 0.9mV/mA (sourcing), 4.0mV/mA (sinking); defines output shift under dynamic load changes in data acquisition circuits) |
| Noise (10Hz–10kHz) | 25µVRMS (low noise preserves SNR in high-resolution analog front-ends) |
| Ripple Rejection | 86dB at 120Hz (rejects AC line artifacts in portable test equipment power rails) |
Pinout & Package
MAX6106EUR is housed in a 3-pin SOT23-3 package (JEDEC MO-178AA), with 1.3mm × 0.8mm footprint and 1.0mm height - optimized for ultra-dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Voltage Supply | Accepts 2.5V–12.6V; internal LDO structure requires ≥200mV headroom above VOUT for regulation |
| 2 (OUT) | Reference Output | Stable 2.048V source/sink node; no external capacitor required for stability with loads <200µA |
| 3 (GND) | Ground Reference | Common return for IN and OUT; must be low-impedance path to minimize ground bounce in mixed-signal systems |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Enables zero-component reference solution for board area–constrained applications like wearables and handheld DMMs |
| Stable with capacitive loads | Operates reliably with CLOAD = 0–∞ when sourcing <200µA; avoids instability traps in buffered sensor interfaces |
| Low 75ppm/°C tempco | Meets industrial-grade drift requirements without calibration; supports unadjusted 12-bit system accuracy |
| 50mV dropout at 1mA | Permits use with 2.5V logic rails or single-cell batteries (2.7–3.6V), extending runtime in portable medical devices |
| ±0.4% initial accuracy | Reduces or eliminates post-production trimming in factory calibration of precision data loggers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3020AIDBZR | 2.048V, 50ppm/°C max, 50µA quiescent current, SOT23-3 - lower tempco but higher initial error (±0.2% vs ±0.4%) | Better drift performance suits higher-accuracy 14-bit systems; lower IQ extends shelf life in energy-harvesting nodes | Select REF3020AIDBZR when tempco dominates budget; MAX6106EUR preferred for cost-sensitive, moderate-accuracy designs |
| ADR3420ARJZ-R7 | 2.048V, 60ppm/°C max, 120µA IQ, 100mV dropout, SOT23-3 - tighter initial tolerance (±0.1%) but higher dropout limits low-VIN use | Required where absolute accuracy exceeds drift control; unsuitable for sub-2.2V supply rails due to higher dropout | Choose ADR3420ARJZ-R7 for calibrated test gear; retain MAX6106EUR for battery voltage–tracking systems needing 50mV dropout |
Compared with REF3020AIDBZR and ADR3420ARJZ-R7, MAX6106EUR offers the lowest dropout and best cost-performance balance for 2.048V references in portable, single-supply systems - trading minor tempco margin for guaranteed 2.5V operation and proven robustness in high-volume consumer electronics.

FAQ
What is the maximum load current the MAX6106EUR can source and sink?
The MAX6106EUR can source up to +5mA and sink up to –2mA while maintaining specified accuracy and regulation. This dual-direction capability allows it to drive both active loads (e.g., ADC reference inputs) and passive loads (e.g., pull-up networks), making MAX6106EUR suitable for bidirectional analog signal chains in portable instrumentation where layout space prohibits discrete buffering.
Does the MAX6106EUR require an output capacitor for stability?
No, the MAX6106EUR is internally compensated and stable with any capacitive load when sourcing less than 200µA. For loads exceeding 200µA, stability may be compromised with capacitances between 0.5nF and 50nF; however, MAX6106EUR remains stable at CLOAD = 0 or ≥100nF. This eliminates mandatory output caps in most portable applications, reducing BOM count and PCB area.
What is the minimum input voltage required for the MAX6106EUR to regulate at 2.048V?
The MAX6106EUR requires a minimum input voltage of 2.5V to maintain regulation at 2.048V output - corresponding to its 50mV dropout specification at 1mA load. At higher loads, dropout increases slightly (e.g., ~70mV at 5mA), so VIN ≥ 2.12V is insufficient; design must ensure VIN ≥ 2.5V across all operating conditions, including battery discharge and line transients.
How does the MAX6106EUR compare to shunt-mode references in terms of supply current efficiency?
Unlike shunt-mode references that waste current through a series resistor, the MAX6106EUR draws only 90µA quiescent current - independent of input voltage (with just 4–8µA/V variation). This means MAX6106EUR consumes ~5× less supply current than typical shunt references biased for 5mA load, significantly extending battery life in always-on sensor nodes and reducing thermal load in sealed enclosures.
Is the MAX6106EUR suitable for automotive applications?
The MAX6106EUR is specified for –40°C to +85°C operation and meets key automotive sub-system requirements (e.g., cabin sensors, infotainment peripherals), but it is not AEC-Q200 qualified. For non-safety-critical, interior-mounted functions like occupancy detection or ambient light sensing, MAX6106EUR provides proven reliability and low dropout - though full automotive qualification requires alternative parts such as the MAX6070 series.
