Product details
Overview
MAX6063AEUR-T from Maxim Integrated is a precision, low-dropout, micropower 3.0V voltage reference in a 3-pin SOT23 package. It delivers ±0.2% initial accuracy, 20ppm/°C max temperature coefficient, and supports 5mA source / 2mA sink load current. Designed for high-accuracy ADC biasing in portable battery-powered systems.
For engineers reviewing the MAX6063AEUR-T datasheet, MAX6063AEUR-T pinout, MAX6063AEUR-T application, or MAX6063AEUR-T equivalent, key selection criteria include dropout voltage (≤200mV at 1mA), supply-current independence from VIN (90µA typ, ≤8µA/V variation), absence of required output capacitor, and guaranteed operation across –40°C to +85°C.
Technical Context
The MAX6063AEUR-T is a three-terminal, series-mode voltage reference using proprietary curvature-correction circuitry and laser-trimmed thin-film resistors. Its internal compensation eliminates need for external capacitors, enabling stable operation with capacitive loads up to 1µF.
It operates over an input range of (VOUT + 0.2V) to 12.6V - i.e., 3.2V to 12.6V - and maintains regulation with ≤0.2% output deviation across full load (0–5mA sourcing) and temperature range. Quiescent current remains stable under line and load transients due to BiCMOS process implementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.2% (2.994V–3.006V at +25°C); enables precise scaling for 3V ADCs and sensors |
| Temp Coefficient | ≤20ppm/°C (max); ensures <±0.5mV drift over –40°C to +85°C ambient |
| Dropout Voltage | ≤200mV at 1mA load; allows operation from 3.2V supply in low-voltage battery systems |
| Supply Current | 90µA typical, ≤8µA/V VIN dependence; minimizes quiescent power in always-on monitoring circuits |
| Load Current | Sources up to 5mA / sinks up to 2mA; drives SAR ADC references and op-amp bias networks directly |
| Noise (0.1–10Hz) | 35µVp-p; low enough for 16-bit+ data acquisition without additional filtering |
| Ripple Rejection | 76dB at 120Hz; suppresses AC ripple from switching regulators feeding the reference |
Pinout & Package
MAX6063AEUR-T is housed in a 3-pin SOT23-3 package (JEDEC MO-178AA), with 1.3mm × 2.9mm footprint and 1.45mm height. Pin 1 is IN, Pin 2 is OUT, Pin 3 is GND - verified per Maxim's official pin configuration diagram and top-mark "FZFV".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage terminal | Accepts 3.2V–12.6V supply; internally regulates to stable 3.0V output; no external resistor needed |
| 2 (OUT) | Precision reference output | Provides low-impedance, low-noise 3.0V reference; stable with 0–1µF capacitive loads |
| 3 (GND) | Analog ground reference | Must be connected to clean system ground; separates reference return from digital/power ground paths |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enables ±0.2% initial accuracy and <20ppm/°C TC without post-package trimming |
| Internally compensated architecture | Eliminates need for external output capacitor - saves PCB area in space-constrained designs |
| Supply-current independence | 90µA quiescent current varies ≤8µA/V across 3.2–12.6V input - simplifies power budgeting |
| Low dropout (200mV max) | Permits use with single-cell Li-ion (3.0–4.2V) or two-cell alkaline (3.2V min) supplies |
| Stable with capacitive loads | Operates reliably with 0–1µF output capacitance - accommodates EMI filtering or local decoupling |

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% init acc, 50ppm/°C TC, 50µA IQ, SOT23-3 | Higher tempco limits use in wide-temperature industrial sensors; lower IQ benefits ultra-low-power IoT nodes | Select when lowest possible quiescent current (<50µA) outweighs tempco requirements |
| ADR3430ARJZ-R7 | 3.0V, ±0.1% init acc, 10ppm/°C TC, 120µA IQ, SOT23-5 | Superior accuracy and TC, but requires 5-pin package and external bypass cap; higher cost | Select when metrology-grade stability justifies added layout complexity and cost |
Compared with REF3030AIDBZR and ADR3430ARJZ-R7, the MAX6063AEUR-T offers best-in-class balance of low dropout (200mV), zero-output-capacitor operation, and industry-standard ±0.2%/20ppm performance - making it optimal for cost-sensitive, space-constrained 3V embedded systems where moderate temperature range suffices.

FAQ
What is the maximum input voltage for MAX6063AEUR-T?
The MAX6063AEUR-T supports an input voltage range from (VOUT + 0.2V) to 12.6V - i.e., 3.2V to 12.6V - as specified in the Electrical Characteristics table. Operation above 12.6V violates Absolute Maximum Ratings and may cause permanent damage. The device is not rated for input transients beyond this limit, even briefly.
Does MAX6063AEUR-T require an external output capacitor?
No, the MAX6063AEUR-T does not require an external output capacitor for stability. Its internally compensated design remains stable with 0–1µF capacitive loads. An optional 0.1µF ceramic capacitor may be added to improve transient response in high-dynamic-load applications, but it is never mandatory - a key advantage for ultra-compact layouts.
What is the load regulation specification for MAX6063AEUR-T?
The MAX6063AEUR-T exhibits load regulation of 0.5–0.9mV/mA when sourcing 0–5mA, and 2.0–6.0mV/mA when sinking –2mA to 0mA. This means output voltage changes by less than 0.9mV per mA increase in sourced load current - critical for maintaining ADC accuracy under varying signal chain conditions.
How does the dropout voltage of MAX6063AEUR-T compare to shunt references?
The MAX6063AEUR-T has a maximum dropout voltage of 200mV at 1mA load, enabling operation from 3.2V supplies. Unlike shunt references that waste current through external resistors, this series-mode device draws only 90µA quiescent current regardless of input voltage - delivering superior efficiency and lower thermal impact in battery-critical designs.
Is MAX6063AEUR-T suitable for automotive applications?
The MAX6063AEUR-T is specified for –40°C to +85°C operation and meets industrial temperature requirements, but it is not AEC-Q200 qualified or characterized for automotive-grade reliability, ESD, or lifetime stress testing. For automotive applications, designers should select explicitly qualified alternatives such as the MAX6070 or ADI's ADR3430 automotive variants.
