Product details
Overview
MAX6002EUR-T from Analog Devices is a precision 2.5V series voltage reference in SOT23-3 package, designed for low-power, wide-input-voltage battery-operated systems. It delivers ±400µA output current capability, 100ppm/°C max temperature coefficient, and 100mV dropout at 400µA load - enabling stable regulation in portable medical sensors, handheld test equipment, and low-voltage ADC/DAC biasing circuits.
For engineers reviewing the MAX6002EUR-T datasheet, MAX6002EUR-T pinout, MAX6002EUR-T application, or MAX6002EUR-T equivalent, key selection criteria include initial accuracy (±1.25%), quiescent supply current (≤45µA), load regulation (0.12µV/µA), and capacitive-load stability up to 2.2nF without external compensation.
Technical Context
The MAX6002EUR-T implements a bandgap-based series voltage reference architecture with internal compensation, eliminating need for external capacitors across its full 0–2.2nF load capacitance range. Its supply current varies only 0.8µA/V over input voltage, ensuring predictable power budgeting in variable-supply environments.
It operates as a three-terminal active regulator: IN accepts (VOUT + 200mV) to 12.6V, OUT delivers a stable 2.500V ±12.5mV (±0.5%), and GND establishes the reference ground. Dropout is specified at 100mV (max) under 400µA sourcing/sinking, supporting operation down to 2.6V input in 2.5V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±12.5mV (±0.5%) - ensures accurate scaling for 12-bit ADCs with ≤1 LSB error at 2.5V FS |
| Initial Accuracy | ±1% max - guarantees VOUT within 24.75mV of nominal before calibration |
| Temp Coefficient | 100ppm/°C max - contributes ≤250µV drift over –40°C to +85°C ambient |
| Quiescent Current | 45µA max - enables >1-year battery life in 10µA-average-power IoT sensor nodes |
| Dropout Voltage | 100mV at 400µA load - allows operation from 2.6V supply in 2.5V rail systems |
| Load Regulation | 0.12µV/µA - maintains <48µV shift across full ±400µA output current range |
| Line Regulation | 8µV/V - limits output change to ≤100µV over 10V input swing (2.7V to 12.6V) |
Pinout & Package
SOT23-3 plastic surface-mount package (3.0mm × 1.7mm × 1.3mm), lead-free and RoHS-compliant, optimized for high-density PCB layouts and reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply Voltage Input | Accepts 2.7V to 12.6V input; must exceed VOUT + 200mV for regulation; supplies internal bandgap core and output stage |
| 2 (OUT) | Reference Voltage Output | Delivers regulated 2.500V; sinks or sources up to ±400µA; stable with 0–2.2nF capacitive loads |
| 3 (GND) | Ground Reference Terminal | Return path for supply current and load current; must be low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Internal Compensation | Eliminates external capacitor requirement - saves PCB area and BOM cost in space-constrained designs |
| Micropower Operation | 45µA max supply current - reduces self-heating and extends battery runtime in always-on monitoring devices |
| Low-Dropout Performance | 100mV dropout at 400µA - enables direct regulation from single-cell Li-ion (3.0–4.2V) or alkaline (2.7–4.5V) supplies |
| Wide Input Range | (VOUT + 200mV) to 12.6V - supports multi-rail systems without dedicated LDO pre-regulation |
| Thermal Hysteresis | 130ppm - ensures repeatable output after thermal cycling, critical for field-deployed instrumentation |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3425ARJZ-R7 | Higher initial accuracy (±0.1%), lower tempco (30ppm/°C), but 95µA max IQ and requires 1µF output cap | Better for metrology-grade instruments; unsuitable where board space or ultra-low IQ is critical | Select when long-term stability and precision outweigh power and layout constraints |
| REF3025AIDBZR | Lower quiescent current (40µA typ), same 2.5V output, but 150ppm/°C tempco and 200mV dropout | Preferred for longest battery life in low-temp-gradient environments; less robust over wide temperature swings | Select when minimizing sleep current is primary, and thermal performance margin is acceptable |
Compared with ADR3425ARJZ-R7 and REF3025AIDBZR, the MAX6002EUR-T uniquely balances ultra-low IQ, minimal dropout, and capacitor-free operation - making it optimal for compact, battery-sensitive designs where moderate accuracy suffices.

FAQ
What is the guaranteed output voltage tolerance for MAX6002EUR-T over temperature?
The MAX6002EUR-T guarantees an output voltage of 2.500V ±12.5mV (±0.5%) over the full –40°C to +85°C operating range. This includes contributions from initial accuracy (±1%), temperature coefficient (≤100ppm/°C), and thermal hysteresis (130ppm), all verified per Analog Devices' production test flow.
Can MAX6002EUR-T operate without an output capacitor?
Yes, the MAX6002EUR-T is internally compensated and remains stable with output capacitance from 0 to 2.2nF. No external capacitor is required for basic regulation, simplifying layout and reducing BOM count - though a small capacitor (e.g., 100pF) may improve transient response in high-dynamic-load applications.
What is the minimum input voltage needed for regulation with MAX6002EUR-T?
The minimum input voltage for regulation is VOUT + 200mV = 2.7V. Below this, the MAX6002EUR-T enters dropout mode and cannot maintain 2.500V output. At 400µA load, dropout voltage is guaranteed ≤100mV, so 2.6V input sustains regulation - critical for single-cell battery systems.
How does MAX6002EUR-T handle reverse current or sinking loads?
The MAX6002EUR-T can both source and sink up to ±400µA continuously at the OUT pin. When sinking current (e.g., into an op-amp input), it maintains regulation as long as IN voltage stays ≥2.7V and power dissipation remains within 320mW limit - enabling bidirectional interfacing with active analog circuitry.
Is MAX6002EUR-T pin-compatible with other members of the MAX6001–MAX6005 family?
Yes, all MAX6001–MAX6005 variants share identical SOT23-3 pinout (IN, OUT, GND), allowing drop-in replacement across output voltages (1.25V to 5.0V) without PCB changes. The MAX6002EUR-T uses top-mark FZCX and operates over –40°C to +85°C, matching mechanical and thermal mounting requirements of the family.
