Product details
Overview
MAX6005EUR+T from Analog Devices is a precision 5.000V, low-dropout series voltage reference in SOT23-3 package, delivering ±0.5% initial accuracy (±25mV), 100ppm/°C max temperature coefficient, and 45µA max quiescent current. It operates from (VOUT + 200mV) to 12.6V input, supports ±400µA load current, and enables stable regulation in space-constrained battery-powered systems.
For engineers reviewing the MAX6005EUR+T datasheet, MAX6005EUR+T pinout, MAX6005EUR+T application, or MAX6005EUR+T equivalent, key selection criteria include dropout voltage at 400µA (100mV typ), load regulation (0.17–1.00 µV/µA), line regulation (25–240 µV/V), and capacitive-load stability up to 2.2nF without external compensation.
Technical Context
The MAX6005EUR+T is a bandgap-based series voltage reference with internal compensation, eliminating need for external capacitors across its 0–2.2nF load range. Its architecture delivers stable 5.000V output while maintaining <0.2% output change over input voltage variations and ±400µA sourcing/sinking capability.
It features micropower operation (45µA max supply current, 0.8µA/V variation), low dropout (100mV at 400µA), and high PSR (72dB at 10Hz–10kHz). Designed for wide-input-voltage battery systems, it avoids shunt-reference inefficiency while retaining cost advantages of discrete references.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050AIDBVR | Higher initial accuracy (±0.05%), lower tempco (3ppm/°C), but 95µA quiescent current and larger SOT23-5 package | Better for metrology-grade systems; unsuitable where board area or ultra-low power is critical | Select REF5050AIDBVR only when sub-10ppm total error budget is required and supply current >45µA is acceptable |
| ADR3450ARJZ-R7 | Similar 5.0V output and SOT23-3 package, but 120ppm/°C tempco and 65µA supply current; requires 1µF output capacitor | Lower cost alternative with relaxed accuracy; capacitor requirement increases layout complexity | Choose ADR3450ARJZ-R7 if tempco tolerance >100ppm/°C is acceptable and board space allows for 1µF ceramic cap |
Compared with REF5050AIDBVR and ADR3450ARJZ-R7, the MAX6005EUR+T offers optimal balance of 5V precision, ultra-low 45µA supply current, capacitor-free operation, and compact SOT23-3 footprint-making it ideal for cost-sensitive, space-constrained, battery-operated instrumentation.

FAQ
What is the maximum input voltage rating for MAX6005EUR+T?
The MAX6005EUR+T has an absolute maximum input voltage of +13.5V referenced to GND. Its operational input range is specified from (VOUT + 200mV) to 12.6V, meaning it functions correctly from 5.2V up to 12.6V. Exceeding 13.5V risks permanent damage per Absolute Maximum Ratings.
Does MAX6005EUR+T require an external output capacitor for stability?
No, the MAX6005EUR+T is internally compensated and stable with output capacitance from 0 to 2.2nF. Unlike many references, it does not require an external capacitor for phase margin or oscillation prevention-reducing bill-of-materials and PCB area in compact designs.
What is the load current capability of MAX6005EUR+T?
The MAX6005EUR+T can source up to +400µA and sink down to –400µA while maintaining output accuracy within specification. This bidirectional drive supports both active loads (e.g., op-amp inputs) and passive loads (e.g., resistor dividers), enabling flexible interface with ADCs, DACs, and comparators.
How does temperature affect the output voltage of MAX6005EUR+T?
The MAX6005EUR+T guarantees a maximum temperature coefficient of 100ppm/°C, meaning output voltage drift is ≤0.5mV over the full –40°C to +85°C range. Measured thermal hysteresis is 130ppm, and long-term stability is 50ppm per 1000 hours at +25°C.
Can MAX6005EUR+T operate from a single 3.7V Li-ion cell?
Yes-the MAX6005EUR+T's minimum input voltage is VOUT + 200mV = 5.2V, so it cannot operate directly from a 3.7V nominal Li-ion cell. However, it works reliably with boosted 5V rails (e.g., using a DC-DC converter) or in systems where input is regulated to ≥5.2V, such as USB-powered portable instruments.
