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 GPS receivers.
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%), supply current variation (0.8µA/V), load regulation (0.12µV/µA), and capacitive-load stability up to 2.2nF without external compensation.
Technical Context
The MAX6002EUR+T is a bandgap-based series voltage reference with internal compensation, eliminating need for external capacitors across its full 0–2.2nF load capacitance range. Its architecture supports operation from (VOUT + 200mV) to 12.6V input while maintaining micropower quiescent current (≤45µA) independent of VIN.
It provides bidirectional output drive (±400µA), enabling direct interface with ADC reference inputs, DAC bias networks, and comparator thresholds. Turn-on settling time is 30µs to 0.1% final value at COUT = 50pF, with ripple rejection of 82dB at 120Hz.

| Dropout Voltage | 100mV at 400µA load (supports regulation from 2.6V input in 2.5V systems) |
| Load Regulation | 0.12µV/µA (maintains <50µV error across full ±400µA output swing) |
| Line Regulation | 8µV/V (limits <100µV shift over 10V input variation) |
| Noise (0.1–10Hz) | 60µVp-p (low enough for 16-bit SAR ADC reference without averaging) |
Pinout & Package
SOT23-3 package: ultra-compact 2.92mm × 1.3mm × 1.02mm footprint with gull-wing leads, optimized for space-constrained portable PCBs.

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 | 2.5V output, 10ppm/°C max tempco, 6µA quiescent current, SOT23-5 package | Lower drift but higher pin count and no bidirectional drive; requires external decoupling | Select for ultra-stable metrology-grade references where 10ppm/°C is mandatory and board space allows SOT23-5 |
| REF3025AIDBZR | 2.5V output, 50ppm/°C max tempco, 50µA quiescent current, SOT23-3 package, no sink capability | Unidirectional output only; lacks ±400µA drive needed for active bias networks | Select when only sourcing is required and tighter tempco than MAX6002EUR+T is acceptable |
Compared with ADR3425ARJZ-R7 and REF3025AIDBZR, the MAX6002EUR+T uniquely combines SOT23-3 footprint, bidirectional ±400µA drive, and 100ppm/°C tempco - making it optimal for space-constrained, low-power systems requiring flexible reference interfacing without layout redesign.

FAQ
What is the maximum input voltage for MAX6002EUR+T?
The MAX6002EUR+T supports an input voltage range from (VOUT + 200mV) to 12.6V, meaning its absolute maximum input is 12.6V. At 2.5V output, minimum valid input is 2.7V. Exceeding 12.6V violates Absolute Maximum Ratings and may cause permanent damage.
Does MAX6002EUR+T require an external output capacitor?
No, the MAX6002EUR+T is internally compensated and stable with output capacitance from 0 to 2.2nF. An external capacitor is optional and only recommended in applications with fast load or supply transients to improve transient response - not for stability.
Can MAX6002EUR+T both source and sink current?
Yes, the MAX6002EUR+T can source up to +400µA and sink down to -400µA from its OUT pin. This bidirectional capability allows direct interfacing with op-amp feedback networks, ADC reference inputs, and active bias circuits without external components.
What is the typical turn-on settling time for MAX6002EUR+T?
The MAX6002EUR+T settles to within 0.1% of final value in 30µs under typical conditions (COUT = 50pF, VIN = 5V). Settling time increases with larger capacitive loads or operation near dropout; worst-case is 220µs for MAX6005, and MAX6002 falls within that range.
Is MAX6002EUR+T specified for automotive temperature range?
No, the MAX6002EUR+T is rated for -40°C to +85°C industrial temperature range only. It is not qualified to AEC-Q100 or extended automotive (-40°C to +125°C) specifications. For automotive applications, consider ADI's AEC-Q100 qualified REF19x or LT665x families instead.
