Product details
Overview
The MAX6065BEUR from Maxim Integrated is a precision, micropower, low-dropout series voltage reference delivering a stable 5.000V output with ±0.4% initial accuracy and 20ppm/°C max temperature coefficient over –40°C to +85°C. It sources up to 5mA or sinks 2mA, draws only 90µA typical supply current, and operates with as little as 5.2V input (VOUT + 200mV), making it ideal for high-accuracy 5V analog signal chains in portable instrumentation and battery-powered data acquisition systems.
For engineers reviewing the MAX6065BEUR datasheet, MAX6065BEUR pinout, MAX6065BEUR application, or MAX6065BEUR equivalent, key selection criteria include its guaranteed 5.000V output tolerance, ultra-low quiescent current independent of input voltage, absence of required output capacitor, stable operation with capacitive loads, and SOT23-3 footprint compatibility with space-constrained PCB layouts.
Technical Context
The MAX6065BEUR is a three-terminal, series-mode voltage reference employing proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve high initial accuracy and low thermal drift. Its internal compensation eliminates need for external stability capacitors, and its supply current varies by only ≤8µA/V across 5.2V–12.6V input range.
It delivers 5.000V output with 200mV max dropout at 1mA load, supports sourcing/sinking capability for driving ADC references and op-amp bias networks, and maintains 65dB PSRR at 120Hz - critical for noise-sensitive precision measurement front-ends operating from noisy DC-DC supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.4% (max) at +25°C - ensures direct compatibility with 5V ADCs and DACs without calibration overhead |
| Temperature Coefficient | 20ppm/°C (max) - enables <±1mV drift over full –40°C to +85°C industrial range |
| Quiescent Supply Current | 90µA (typ), ≤125µA (max) - extends battery life in always-on portable sensors and handheld meters |
| Dropout Voltage | 200mV (max) at 1mA load - allows operation from 5.2V input, compatible with single-cell Li+ or regulated 5V rails |
| Load Regulation | 0.9mV/mA (max) sourcing - maintains tight output stability under varying ADC reference current demands |
| Line Regulation | 550µV/V (max) - rejects ripple and variation from upstream power stages without additional filtering |
| Noise (0.1Hz–10Hz) | 60µVp-p - minimizes contribution to system noise floor in high-resolution (≥16-bit) data converters |
Pinout & Package
MAX6065BEUR is housed in a 3-pin SOT23-3 package (JEDEC MO-178AA), with 1.3mm × 0.8mm footprint and 0.95mm height - optimized for compact, high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input Voltage Supply | Accepts 5.2V to 12.6V input; requires no external series resistor - unlike shunt references, supply current scales only with load demand |
| 2 (OUT) | Precision Reference Output | Delivers regulated 5.000V; stable with 0–1µF capacitive loads; no external capacitor required for stability |
| 3 (GND) | Analog Ground Reference | Must be connected to clean, low-impedance ground plane; separates reference return path from digital or power ground currents |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 90µA typical, supply-voltage-independent - reduces standby power in battery-backed systems by >90% vs. legacy references |
| No output capacitor required | Fully internally compensated - saves ≥1mm² board area and eliminates capacitor aging, leakage, and ESR-related drift |
| High output drive capability | ±5mA sourcing/sinking - directly drives ADC reference inputs, op-amp bias networks, and small logic loads without buffer amplifiers |
| Low dropout voltage | 200mV max at 1mA - enables use with low-headroom supplies such as buck regulators set to 5.2V |
| Stable with capacitive loads | Operates robustly with 0–1µF output capacitance - simplifies layout in mixed-signal systems where decoupling caps are unavoidable |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050AIDBVR | 5.0V output, ±0.05% initial accuracy, 3ppm/°C TC, 1.2mA quiescent current | Higher precision and lower drift, but 13× higher supply current and larger SOT23-5 package | Select when absolute accuracy and long-term stability outweigh battery life and board area constraints |
| ADR3450ARJZ-R7 | 5.0V output, ±0.1% initial accuracy, 10ppm/°C TC, 120µA quiescent current, 300mV dropout | Slightly better TC and accuracy than MAX6065BEUR, but higher dropout and less sink current (1mA) | Select when tighter drift spec is needed and input headroom ≥5.3V is available |
Compared with REF5050AIDBVR and ADR3450ARJZ-R7, the MAX6065BEUR offers the lowest quiescent current and smallest footprint among 5V references with ±0.4% accuracy, making it optimal for size- and power-constrained portable instrumentation where moderate precision suffices.

FAQ
What is the maximum input voltage rating for the MAX6065BEUR?
The MAX6065BEUR has an absolute maximum input voltage of +13.5V referenced to GND. However, its specified operating input range is (VOUT + 0.2V) to 12.6V - i.e., 5.2V to 12.6V - with guaranteed performance including line regulation, dropout, and accuracy. Exceeding 12.6V may degrade long-term reliability even if below the absolute maximum.
Does the MAX6065BEUR require an external output capacitor for stability?
No, the MAX6065BEUR is fully internally compensated and does not require an external output capacitor for stability. It remains stable with 0–1µF capacitive loads. Adding a capacitor (e.g., 0.1µF ceramic) improves transient response under step-load conditions but is optional - a key advantage for ultra-compact PCB layouts where every mm² matters.
What is the guaranteed initial accuracy of the MAX6065BEUR at +25°C?
The MAX6065BEUR guarantees ±0.4% initial output voltage accuracy at +25°C, corresponding to a 5.000V output ranging from 4.980V to 5.020V. This "B-grade" accuracy is confirmed by 100% production testing and applies across the full –40°C to +85°C operating temperature range per design guarantee.
Can the MAX6065BEUR sink current, and how much?
Yes, the MAX6065BEUR can both source and sink current. It guarantees ±2mA sink capability - meaning it can absorb up to 2mA from the output node into GND - enabling bidirectional reference buffering, active load regulation, and compatibility with circuits requiring pull-down functionality alongside standard sourcing.
How does the supply current of the MAX6065BEUR vary with input voltage?
The MAX6065BEUR exhibits near-constant quiescent supply current: typical 90µA, max 125µA across its full 5.2V–12.6V input range. Its supply current variation is limited to ≤8µA/V - significantly more stable than shunt references whose current inherently scales with input voltage and worst-case load.
