Product details
Overview
MAX6100EUR+T from Maxim Integrated is a 1.8V, low-dropout (50mV at 1mA), micropower (90µA typical) series-mode voltage reference in a 3-pin SOT23 package, featuring ±0.4% initial accuracy, 75ppm/°C max temperature coefficient, and no external capacitor requirement-used for precision ADC/DAC biasing and battery-powered sensor signal conditioning.
For engineers reviewing the MAX6100EUR+T datasheet, MAX6100EUR+T pinout, MAX6100EUR+T application, or MAX6100EUR+T equivalent, this page delivers verified electrical specs, real-world load/line regulation behavior, thermal stability data, and validated alternative options for portable, low-voltage, high-accuracy analog systems.
Technical Context
The MAX6100EUR+T employs a proprietary curvature-correction circuit with laser-trimmed thin-film resistors to achieve 75ppm/°C max TCVOUT over –40°C to +85°C. Its series-mode architecture eliminates dependency on external bias resistors and enables supply current virtually independent of VIN (4–8µA/V variation).
Internally compensated for stability with any capacitive load when sourcing <200µA, it delivers 5mA source / 2mA sink capability while maintaining 0.9mV/mA load regulation (source) and 4.0mV/mA (sink), enabling direct interface with precision converters and low-power microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.800V ±0.4% (1.793V–1.807V at +25°C); sets precise bias point for 1.8V-domain ADCs and analog front-ends. |
| Temp Coefficient | 75ppm/°C max (–40°C to +85°C); ensures ≤1.35mV drift across full industrial range-critical for uncalibrated portable instruments. |
| Dropout Voltage | 50mV at 1mA load; allows operation from 2.5V input down to 1.85V, supporting single-cell Li-ion or dual-cell alkaline systems. |
| Quiescent Current | 90µA typical, 125µA max; enables >1-year battery life in 10µA-average IoT sensors using coin cells. |
| Load Regulation | 0.9mV/mA (source), 4.0mV/mA (sink); maintains output stability during dynamic MCU wake/sleep transitions or sensor burst reads. |
| Ripple Rejection | 86dB at 120Hz; suppresses switching regulator noise in mixed-signal power domains without additional filtering. |
| Long-Term Stability | 50ppm/1000hr; guarantees minimal calibration drift in field-deployed medical or industrial monitoring equipment. |
Pinout & Package
MAX6100EUR+T uses a 3-pin SOT23-3 package (JEDEC MO-178AA), 1.45mm × 2.9mm footprint, 1.1mm height, with gull-wing leads. Pin 1 = IN (supply input), Pin 2 = OUT (1.8V reference output), Pin 3 = GND (ground reference).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Input | Accepts 2.5V–12.6V input; internal LDO structure rejects ripple and enables ultra-low quiescent current independent of VIN. |
| 2 (OUT) | Reference Output | Delivers stable 1.8V ±0.4%; directly drives ADC REF pins, DAC VREF, or op-amp bias networks without buffering. |
| 3 (GND) | Ground Reference | Low-impedance return path; must be connected to clean analog ground to preserve 75ppm/°C tempco and noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Stable with 0–∞ load capacitance when sourcing <200µA; eliminates PCB area and BOM cost in space-constrained wearables. |
| Ultra-low supply current | 90µA typical, varying only 4–8µA/V with VIN; outperforms shunt references by >5× in battery runtime for always-on sensing nodes. |
| Low dropout operation | 50mV dropout at 1mA enables use with 2.5V supplies-supports legacy 1.8V logic rails powered from single Li-ion cells. |
| High output drive | Sources 5mA / sinks 2mA; directly interfaces with SAR ADC reference inputs, op-amp gain-setting networks, and digital potentiometers. |
| Laser-trimmed accuracy | ±0.4% initial tolerance at +25°C; reduces system calibration overhead in portable DMMs and handheld test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3418ARJZ-R7 | 1.8V output, ±0.1% initial accuracy, 30ppm/°C tempco, 125µA IQ, SOT23-3 | Higher accuracy and lower tempco but 38% higher quiescent current; suited for lab-grade instruments where battery life is secondary. | Select ADR3418ARJZ-R7 when <30ppm/°C drift and <±0.1% error are mandatory; accept trade-off in power consumption. |
| REF3018AIDBZR | 1.8V output, ±0.2% initial accuracy, 50ppm/°C tempco, 100µA IQ, SOT23-3 | Better tempco than MAX6100EUR+T but requires 1µF output capacitor for stability; adds BOM cost and board area. | Choose REF3018AIDBZR if system already includes output capacitance and tighter tempco is prioritized over capacitor elimination. |
Compared with ADR3418ARJZ-R7 and REF3018AIDBZR, MAX6100EUR+T uniquely balances ultra-low IQ (90µA), capacitor-free operation, and industrial-grade tempco (75ppm/°C) in a cost-sensitive SOT23 package-making it optimal for consumer portable electronics where size, battery life, and BOM simplicity are co-primary constraints.

FAQ
What is the maximum input voltage for MAX6100EUR+T?
The MAX6100EUR+T supports an input voltage range of 2.5V to 12.6V. Absolute maximum rating is +13.5V on the IN pin relative to GND. Operation above 12.6V risks exceeding safe power dissipation limits in the SOT23 package, especially at elevated ambient temperatures.
Does MAX6100EUR+T require an output capacitor for stability?
No, MAX6100EUR+T is internally compensated and stable with any capacitive load when sourcing less than 200µA. For loads exceeding 200µA, stability is maintained with CLOAD < 0.5nF or > 50nF; intermediate values may cause oscillation. Most precision ADC applications operate safely without added capacitance.
What is the load current capability of MAX6100EUR+T?
MAX6100EUR+T can source up to 5mA and sink up to 2mA while maintaining specified accuracy and regulation. Load regulation is 0.9mV/mA (source) and 4.0mV/mA (sink), meaning output voltage shifts ≤4.5mV under full 5mA sourcing and ≤8mV under full 2mA sinking.
How does MAX6100EUR+T compare to shunt voltage references in power efficiency?
Unlike shunt references that waste supply current through a series resistor, MAX6100EUR+T draws only 90µA quiescent current-virtually independent of input voltage. This eliminates wasted bias current, improving battery life by >5× in always-on applications compared to equivalent shunt-based solutions.
Is MAX6100EUR+T suitable for automotive applications?
MAX6100EUR+T is specified for –40°C to +85°C operation and meets industrial temperature requirements, but it is not AEC-Q200 qualified. For non-safety-critical automotive cabin modules (e.g., infotainment sensors), it may be used with system-level validation; for engine bay or ADAS applications, AEC-Q100-qualified alternatives are required.
