Product details
Overview
MAX6063AEUR+T from Maxim Integrated is a precision, low-dropout, micropower series voltage reference delivering a stable 3.000V output with ±0.2% 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 quiescent current, and operates with as little as 200mV dropout at 1mA load-ideal for battery-powered precision ADC biasing in portable instrumentation.
For engineers reviewing the MAX6063AEUR+T datasheet, MAX6063AEUR+T pinout, MAX6063AEUR+T application, or MAX6063AEUR+T equivalent, key selection criteria include its SOT23-3 package footprint, supply-independent ultra-low quiescent current, absence of required output capacitor, and guaranteed performance across industrial temperature range without external compensation.
Technical Context
The MAX6063AEUR+T is a three-terminal series-mode voltage reference using 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 capacitors, simplifying layout in space-constrained designs.
It operates from (VOUT + 0.2V) to 12.6V input, maintains stable regulation under capacitive loads, and exhibits 76dB power-supply rejection at 120Hz. The device delivers 35µVp-p (0.1Hz–10Hz) noise and supports fast turn-on settling (115µs to 0.1% with 50pF load).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.2% at +25°C - enables direct interface with 3V ADC reference inputs without scaling |
| Temp Coefficient | 20ppm/°C (max) - ensures ≤±0.6mV drift over full –40°C to +85°C range for stable measurement systems |
| Quiescent Current | 90µA (typ), ≤125µA (max) - extends battery life in always-on portable sensors and data loggers |
| Dropout Voltage | 200mV (max) at 1mA load - allows operation from single-cell Li-ion (3.0V min) or two-cell alkaline supplies |

| Noise (0.1–10Hz) | 35µVp-p - minimizes added uncertainty in high-resolution (≥16-bit) analog signal chains |
| Line Regulation | 400µV/V (max) - maintains output stability despite input rail variations in noisy DC-DC environments |
Pinout & Package
MAX6063AEUR+T is housed in a 3-pin SOT23-3 package (JEDEC MO-178AA), with 1.3mm × 0.8mm footprint and 1.0mm height - compatible with standard pick-and-place and reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 (OUT) | Precision Reference Output | Provides regulated 3.000V; stable with capacitive loads; no external capacitor needed for stability |
| 3 (GND) | Analog Ground Reference | Common return for IN and OUT; must be connected to clean system ground plane for optimal noise performance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 90µA typical - reduces standby power by >90% vs. legacy bandgap references, critical for coin-cell devices |
| No output capacitor required | Fully internally compensated - eliminates 0.1µF ceramic cap, saving PCB area and BOM cost in wearables |
| Low dropout voltage | 200mV max at 1mA - enables use with low-headroom supplies such as buck regulators set to 3.3V |
| High output drive capability | ±5mA sourcing/sinking - directly powers multiple SAR ADC references or sensor excitation circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3430ARJZ-R7 | 3.0V output, ±0.1% initial accuracy, 10ppm/°C TC, 4.5µA quiescent current - lower power but lower drive (10mA sink only, no source spec) | Better for ultra-low-power sleep modes; unsuitable for sourcing-heavy loads like multiple op-amp bias networks | Select when lowest possible quiescent current dominates; verify sink-only load compatibility |
| REF3030AIDBZR | 3.0V output, ±0.2% initial accuracy, 50ppm/°C TC, 40µA quiescent current - higher drift, lower noise (25µVp-p) | Acceptable for cost-sensitive consumer devices where ±1.5mV total drift is tolerable | Select for budget-limited designs with relaxed thermal stability requirements; avoid in industrial-grade instruments |
Compared with ADR3430ARJZ-R7 and REF3030AIDBZR, the MAX6063AEUR+T uniquely balances ultra-low quiescent current (90µA), high output drive (5mA source), and tight thermal stability (20ppm/°C) in a single SOT23-3 package-making it optimal for portable test equipment and battery-powered precision sensing where both power and accuracy are constrained.

FAQ
What is the maximum input voltage rating for the MAX6063AEUR+T?
The MAX6063AEUR+T 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 - meaning minimum valid input is 3.2V for reliable regulation. Operation above 12.6V risks exceeding absolute ratings and invalidating parametric guarantees.
Does the MAX6063AEUR+T require an output capacitor for stability?
No, the MAX6063AEUR+T is internally compensated and does not require an external output capacitor for stability. It remains stable with capacitive loads up to at least 1µF. An optional 0.1µF ceramic capacitor may be added to improve transient response in high-dynamic-load applications, but it is never mandatory.
What is the guaranteed initial accuracy of the MAX6063AEUR+T at +25°C?
The MAX6063AEUR+T is specified with ±0.2% initial accuracy at +25°C - corresponding to a 3.000V output tolerance of ±6mV (2.994V to 3.006V). This grade ('A' suffix) is confirmed across 100% production testing and applies over the full –40°C to +85°C operating range per design guarantee.
Can the MAX6063AEUR+T sink and source current simultaneously?
No - the MAX6063AEUR+T operates as a unidirectional series reference: it sources up to 5mA into a load connected between OUT and GND, or sinks up to 2mA from a load connected between OUT and a positive supply. It cannot source and sink concurrently; the net load current must be either positive (source) or negative (sink), not both.
How does the MAX6063AEUR+T compare to shunt voltage references in terms of supply current efficiency?
Unlike shunt references that draw constant current independent of load, the MAX6063AEUR+T draws only 90µA quiescent current - virtually independent of input voltage (≤8µA/V variation). This eliminates wasted current through external resistors and avoids overdesigning bias networks, making it significantly more efficient in battery-powered systems where load current varies dynamically.
