Product details
Overview
The MAX6101EUR-T from Maxim Integrated is a 1.25V, low-dropout (50mV at 1mA), micropower (90µA typical quiescent current) series-mode voltage reference in a 3-pin SOT23 package, featuring ±0.4% initial accuracy, 75ppm/°C max temperature coefficient, and stable operation without external output capacitance-used for precision ADC/DAC biasing and battery-powered sensor signal conditioning.
For engineers reviewing the MAX6101EUR-T datasheet, MAX6101EUR-T pinout, MAX6101EUR-T application, or MAX6101EUR-T equivalent, this device supports high-accuracy analog front-ends in space-constrained portable systems where supply independence, ultra-low current draw, and dropout performance below 100mV are critical selection criteria.
Technical Context
The MAX6101EUR-T employs a proprietary curvature-correction circuit with laser-trimmed thin-film resistors to achieve low thermal drift. Its series-mode architecture eliminates dependency on external bias resistors and enables supply-current stability across 2.5V–12.6V input range with only 4µA/V variation.
Internally compensated for capacitive loads up to 1µF, it delivers 5mA sourcing and 2mA sinking capability while maintaining 0.1% settling in 50µs (typical). Dropout voltage remains ≤50mV at 1mA load, enabling operation near battery end-of-life in 1.5V–3.6V systems.

Pinout & Package
MAX6101EUR-T uses a 3-pin SOT23-3 package (JEDEC MO-178AA) with 1.3mm × 2.9mm footprint and 0.95mm height. Pin 1 is IN (input voltage), Pin 2 is OUT (1.25V reference output), Pin 3 is GND (ground reference).

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF191GS | 1.25V output, 50ppm/°C max tempco, 100µA quiescent current, SO-8 package | Larger footprint; higher accuracy but 10× higher supply current and no SOT23 option | Select when lower tempco outweighs size and power constraints |
| ADR3412ARJZ-R7 | 1.2V output, 30ppm/°C max tempco, 120µA quiescent current, SOT23-3 package | Different output voltage (1.2V vs 1.25V); tighter tempco but higher current and reduced headroom for 1.25V systems | Select only if system redesign accommodates 1.2V reference and requires <50ppm/°C drift |
Compared with REF191GS and ADR3412ARJZ-R7, the MAX6101EUR-T uniquely balances SOT23-3 size, 1.25V output, ultra-low 90µA current, and 75ppm/°C drift-making it optimal for space- and battery-limited designs where exact 1.25V scaling is required.

FAQ
What is the minimum input voltage required for stable operation of the MAX6101EUR-T?
The MAX6101EUR-T requires a minimum input voltage of VOUT + 200mV = 1.45V to maintain regulation. Its specified input range is 2.5V to 12.6V, but functional operation begins at 1.45V. Below 2.5V, performance parameters such as line regulation and dropout are not guaranteed per datasheet specifications, though the device remains operational down to 1.45V with increased dropout sensitivity.
Does the MAX6101EUR-T require an external output capacitor for stability?
No, the MAX6101EUR-T does not require an external output capacitor for stability. It is internally compensated and remains stable with capacitive loads from 0 to 1µF. An optional 1µF ceramic capacitor may be added to improve transient response in high-dynamic-load applications, but omission saves PCB area and reduces BOM count-critical in ultra-compact designs like hearing aids or implantable sensors.
How does the MAX6101EUR-T compare to shunt-mode references in terms of supply current efficiency?
Unlike shunt-mode references that waste current through a series resistor, the MAX6101EUR-T draws only 90µA quiescent current independent of input voltage (with ≤4µA/V variation). This eliminates wasted bias current and enables efficient operation across wide input ranges-e.g., from 3.0V to 12.6V-without redesigning the supply network, directly extending battery life in multi-cell or adapter-powered portable instruments.
Can the MAX6101EUR-T sink current, and what is its maximum sink capability?
Yes, the MAX6101EUR-T can both source and sink current. It sinks up to 2mA while maintaining output regulation, with load regulation specified at 8mV/mA (max). This bidirectional capability allows use in ratiometric sensor bridges, active filter biasing, and DAC output buffering where the reference must absorb current during signal transitions-unlike many fixed-reference ICs limited to sourcing only.
What is the long-term stability specification for the MAX6101EUR-T, and how is it measured?
The MAX6101EUR-T exhibits 50ppm/1000hr long-term stability, measured as output voltage drift after 1000 hours of continuous operation at +25°C. This parameter reflects silicon-level aging behavior and supports reliability planning for products with >5-year field lifetimes, such as industrial controllers and medical diagnostic devices where recalibration intervals must exceed 2 years.
