Product details
Overview
MAX6035AAUR30+T from Analog Devices is a high-voltage, precision micropower series-mode voltage reference delivering a stable 3.0V output with ±0.2% initial accuracy and 25ppm/°C max temperature coefficient over –40°C to +125°C. It draws only 73µA quiescent current, sources up to 10mA, sinks 2mA, and operates from 4.9V to 33V supply-ideal for Li+ battery chargers and 12-bit data converters.
For engineers reviewing the MAX6035AAUR30+T datasheet, MAX6035AAUR30+T pinout, MAX6035AAUR30+T application, or MAX6035AAUR30+T equivalent, key selection considerations include ultra-low supply current independence from VIN, no external compensation capacitor requirement, stability with up to 5µF capacitive load, and SOT23-3 footprint compatibility in space-constrained industrial and portable systems.
Technical Context
The MAX6035AAUR30+T is a three-terminal series-mode reference using proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve 25ppm/°C (–40°C to +85°C) and ±0.2% initial accuracy. Its internal compensation eliminates need for external stabilization capacitors while maintaining stability with loads up to 5µF.
Unlike shunt references, it draws near-constant 73µA supply current across 4.9V–33V input range (ΔIIN/ΔVIN ≤ 0.7µA/V), enabling efficient battery operation. Dropout voltage is 1.75V at 10µA and 2.25V at 10mA, supporting wide headroom flexibility in high-supply-voltage applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.2% (±6mV) at +25°C - ensures 12-bit ADC full-scale accuracy without calibration |
| Tempco (–40°C to +85°C) | 25ppm/°C max - limits drift to ±2.1mV over 85°C span, critical for precision sensor front-ends |
| Quiescent Current | 73µA typical, 95µA max - enables >1-year runtime on coin-cell batteries in always-on monitoring |
| Supply Range | 4.9V to 33V - supports direct connection to 12V/24V industrial rails and unregulated battery inputs |
| Capacitive Load Stability | Stable with 0–5µF output capacitance - eliminates need for layout-sensitive compensation networks |
| Line Regulation | 24µV/V max - maintains <0.001% output change per volt input variation, vital for noisy power domains |
| Load Regulation | 96µV/mA max sourcing - holds output within ±0.1% across full 10mA load range |
Pinout & Package
MAX6035AAUR30+T is housed in a 3-pin SOT23-3 package (JEDEC MO-178AA, Analog Devices U3-1), with 1.3mm × 0.8mm footprint and 0.95mm height - optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Voltage Supply | Accepts 4.9V–33V; internally regulates to generate precise 3.0V reference; requires no external series resistor |
| 2 (OUT) | Reference Output | Low-impedance 3.0V source/sink node; stable with 0–5µF capacitive loads; no external capacitor required |
| 3 (GND) | Ground Reference | Return path for input current and load current; must be low-impedance connection to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Proprietary tempco correction | 25ppm/°C max (–40°C to +85°C) achieved via on-die curvature compensation - outperforms REF02/REF43 by >2× |
| Laser-trimmed thin-film resistors | Enables ±0.2% initial accuracy without post-package trimming - reduces test cost and improves lot-to-lot consistency |
| Supply-current independence | 73µA typical across 4.9V–33V - eliminates wasted bias current seen in shunt references, maximizing battery life |
| No external compensation cap | Internally compensated for unity-gain stability - saves 1–2 mm² board area vs. competitors requiring 100nF–1µF ceramic caps |
| High sink/source capability | Sinks 2mA / sources 10mA - drives ADC reference inputs, op-amp bias networks, and DAC buffers directly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3030AIDBZR | 3.0V, ±0.2%, 50ppm/°C (–40°C to +125°C), 50µA IQ, SOT23-3 | Higher tempco (50ppm/°C vs. 25ppm/°C); lower IQ but less stable over temperature | Choose REF3030AIDBZR only if tempco <25ppm/°C is not required and lowest possible IQ is critical |
| ADR3430ARJZ-R7 | 3.0V, ±0.1%, 10ppm/°C (–40°C to +125°C), 120µA IQ, SOT23-5 | Superior accuracy and tempco, but higher IQ and 5-pin SOT23 requires PCB redesign | Choose ADR3430ARJZ-R7 when ±0.1% and 10ppm/°C are mandatory, accepting higher current and layout change |

FAQ
What is the maximum operating temperature range for MAX6035AAUR30+T?
The MAX6035AAUR30+T is specified for continuous operation from –40°C to +125°C. This extended temperature grade is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, making it suitable for under-hood automotive modules and industrial motor controls where ambient temperatures exceed +85°C.
Does MAX6035AAUR30+T require an external output capacitor?
No, MAX6035AAUR30+T does not require an external output capacitor for stability-it is internally compensated and guaranteed stable with 0–5µF capacitive loads. An optional 0.1µF ceramic capacitor may be added to improve transient response in high-dynamic-load applications, but it is not necessary for basic functionality.
What is the minimum input voltage needed for MAX6035AAUR30+T to regulate at 3.0V?
The minimum input voltage for MAX6035AAUR30+T is 4.9V at –40°C to +125°C, derived from dropout voltage specifications (1.75V at 10µA, 2.25V at 10mA) plus the 3.0V output. Below 4.9V, regulation degrades; operation is guaranteed only above this threshold across the full temperature range.
How does MAX6035AAUR30+T compare to REF02 in power consumption?
MAX6035AAUR30+T draws 73µA typical supply current-14× lower than REF02's ~1mA typical consumption. This reduction stems from its series-mode architecture versus REF02's shunt topology, eliminating wasteful bias current and enabling multi-year battery life in portable equipment.
Is MAX6035AAUR30+T pin-compatible with other MAX6035 variants?
Yes, all MAX6035 variants in the SOT23-3 package-including MAX6035AAUR25+T and MAX6035AAUR50+T-share identical pinout (IN, OUT, GND), allowing design reuse across 2.5V/3.0V/5.0V reference needs without PCB changes. The top-mark codes (e.g., FZMY) differ, but mechanical and electrical pin mapping is identical.
