Product details
Overview
MAX6006BEUR-T from Maxim Integrated is a precision 1.25V two-terminal shunt voltage reference in a 3-pin SOT23 package, featuring 0.5% initial accuracy, 75ppm/°C temperature coefficient, <1µA guaranteed operating current, and operation over -40°C to +85°C. It serves as a low-power, space-constrained voltage reference for battery-powered instrumentation and precision analog signal chains.
For engineers reviewing the MAX6006BEUR-T datasheet, MAX6006BEUR-T pinout, MAX6006BEUR-T application, or MAX6006BEUR-T equivalent, key selection criteria include ultra-low quiescent current, tight initial tolerance under minimal bias, thermal stability in portable environments, and compatibility with standard shunt regulator topologies requiring <2mA compliance current.
Technical Context
The MAX6006BEUR-T implements a laser-trimmed series bandgap core with on-chip thin-film resistors, delivering stable 1.25V output across its full operating current range (0.5µA to 2mA). Its two-terminal architecture requires external biasing via a pull-up resistor and mandates ≥0.01µF output bypass capacitance for stability.
It operates as a precision shunt element-sinking current to regulate voltage at its OUT terminal-enabling use in high-impedance sensing nodes, low-power ADC references, and current-source configurations where supply headroom is limited and power budget is sub-10µW.

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040BIM3-1.2 | 1.225V output, ±0.2% initial accuracy, 100ppm/°C TC, 60µA min operating current | Higher power consumption limits use in sub-µA systems; tighter initial accuracy but worse thermal stability | Select when absolute initial accuracy outweighs thermal drift and ultra-low IQ requirements |
| TLVH431IDBZR | Adjustable 1.24V reference, ±0.5% accuracy, 100ppm/°C TC, 80µA min current, 3-pin SOT23 | Requires two external resistors for fixed 1.25V; higher IQ and noise limit DC precision use | Choose only if adjustable output or higher sink current (>15mA) is needed-otherwise MAX6006BEUR-T offers superior low-IQ performance |
Compared with LM4040BIM3-1.2 and TLVH431IDBZR, the MAX6006BEUR-T delivers uniquely low 0.5µA minimum operating current and 30µVP-P noise-making it the only option among the three suitable for true nanoamp-biased, high-resolution measurement systems.

FAQ
What is the guaranteed minimum operating current for MAX6006BEUR-T?
The MAX6006BEUR-T guarantees a minimum operating current of 0.5µA, with typical operation starting at 1.0µA. This value is defined as the lowest reverse current at which the output voltage remains within ±0.2% of its nominal 1.25V value-enabling reliable startup and regulation in nanoamp-biased circuits where the MAX6006BEUR-T is often used as a reference for ultra-low-power sensors.
Does MAX6006BEUR-T require an external capacitor, and if so, what value?
Yes, the MAX6006BEUR-T requires a minimum 0.01µF capacitor connected between OUT and GND for stability. This bypass capacitor suppresses high-frequency oscillation and improves transient response during load or supply steps. Larger values (e.g., 0.1µF) may be added in noisy environments or where enhanced step-load immunity is needed-without affecting the MAX6006BEUR-T's core regulation performance.
Can MAX6006BEUR-T replace LM4040 in existing designs?
The MAX6006BEUR-T can replace LM4040 variants in low-current applications, but only with circuit review. While both are 3-pin shunt references, the MAX6006BEUR-T draws <1µA versus LM4040's ~60µA minimum, requiring bias resistor recalculation. Also, the MAX6006BEUR-T's 1.25V output differs from common LM4040 versions (1.225V, 2.048V, 2.5V, 4.096V); direct substitution is valid only for 1.25V-targeted designs using the MAX6006BEUR-T.
What is the thermal hysteresis specification for MAX6006BEUR-T?
The MAX6006BEUR-T exhibits ≤200ppm thermal hysteresis-the maximum change in its +25°C output voltage after cycling between -40°C and +85°C. This parameter reflects mechanical stress memory in the package and bandgap core, and is critical for applications like field-calibrated instrumentation where repeatable voltage output after temperature excursions is mandatory. The MAX6006BEUR-T's hysteresis is fully characterized and guaranteed per the datasheet.
Is MAX6006BEUR-T qualified for automotive applications?
No, the MAX6006BEUR-T is not AEC-Q100 qualified. Only the MAX6008AEUR/V+T variant (2.5V, Grade A) carries AEC-Q100 qualification. The MAX6006BEUR-T is specified for industrial temperature range (-40°C to +85°C) and intended for commercial and industrial portable equipment-not automotive ECUs or under-hood modules requiring automotive-grade reliability screening.
