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 supply, supports ±400µA load current, and enables stable operation with 0–2.2nF capacitive loads - ideal for battery-powered instrumentation requiring tight voltage regulation under wide input variation.
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 (100–200mV), line regulation (25–240µV/V), load regulation (0.17–1.00µV/µA), and long-term stability (50ppm/1000hrs) in space-constrained portable systems.
Technical Context
The MAX6005EUR-T implements a bandgap-based series voltage reference architecture with internal compensation, eliminating external capacitors. Its output remains stable across 0–2.2nF load capacitance without oscillation, and it maintains regulation during supply transients via low line regulation (25µV/V typical) and fast turn-on settling (220µs to 0.1% at VIN = 5.5V).
It functions as a three-terminal active reference: IN draws supply current independent of load (0.8µA/V variation), OUT delivers regulated 5.000V with bidirectional ±400µA sourcing/sinking capability, and GND establishes the reference ground. Dropout is defined at ≤0.2% VOUT deviation, measured at VIN = 5.5V for this variant.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3450ARJZ-R7 | 5.0V output, 10ppm/°C TC (vs. 100ppm/°C), 4.5µA IQ, but requires ≥1µF output cap for stability | Better TC and lower IQ, yet incompatible with zero-capacitance layouts and higher-cost | Select when ultra-low drift (<10ppm/°C) and sub-5µA IQ justify added capacitor and cost |
| REF3050AIDBZR | 5.0V output, 50ppm/°C TC, 40µA IQ, stable with 0–10nF load, but 350mV dropout at 400µA | Wider CLOAD range and lower TC, but higher dropout limits use below 5.35V input | Select when broader capacitive-load flexibility is needed and input voltage exceeds 5.4V |
Compared with ADR3450ARJZ-R7 and REF3050AIDBZR, the MAX6005EUR-T offers the lowest system-level cost and smallest footprint for mid-accuracy (±0.5%), low-dropout (100mV) applications where zero-output-capacitor operation is mandatory.

FAQ
What is the maximum input voltage rating for the MAX6005EUR-T?
The MAX6005EUR-T has an absolute maximum input voltage of +13.5V referenced to GND. Its operational supply range is specified from (VOUT + 200mV) to 12.6V - meaning minimum functional input is 5.2V, and maximum recommended continuous input is 12.6V per the Electrical Characteristics table. Exceeding 13.5V risks permanent damage.
Does the MAX6005EUR-T require an external output capacitor?
No, the MAX6005EUR-T does not require an external output capacitor. It is internally compensated and guaranteed stable with capacitive loads from 0 to 2.2nF. Adding a capacitor may improve transient response in high-dynamic-load applications but is optional and unnecessary for basic regulation stability.
What is the load current capability of the MAX6005EUR-T?
The MAX6005EUR-T can source up to +400µA and sink up to –400µA from its OUT pin while maintaining regulation within specifications. This bidirectional capability allows it to drive resistive loads, ADC reference inputs, and op-amp bias networks without external buffering in most low-power applications.
How does temperature affect the output voltage of the MAX6005EUR-T?
The MAX6005EUR-T exhibits a maximum temperature coefficient of 100ppm/°C, meaning its output voltage may drift up to ±0.5mV over the full –40°C to +85°C range. Additionally, thermal hysteresis contributes up to 130ppm (±0.65mV) shift after temperature cycling, and long-term stability adds ±0.25mV drift over 1000 hours at +25°C.
Can the MAX6005EUR-T be used in automotive applications?
The MAX6005EUR-T is rated for –40°C to +85°C operation and meets industrial temperature requirements, but it is not AEC-Q200 qualified. For non-safety-critical automotive body electronics (e.g., infotainment sensors), it may be deployed with proper system-level validation; however, mission-critical powertrain or ADAS applications require AEC-Q100-qualified alternatives.
