Product details
Overview
MAX6063BEUR from Maxim Integrated is a precision, low-dropout, micropower series voltage reference delivering a stable 3.0V 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 3.2V input (VOUT + 200mV). It is used in high-accuracy ADC biasing, portable instrumentation, and battery-powered 3V systems where space and power efficiency are critical.
For engineers reviewing the MAX6063BEUR datasheet, MAX6063BEUR pinout, MAX6063BEUR application, or MAX6063BEUR equivalent, key selection criteria include its 3.0V output tolerance, ultra-low quiescent current, dropout voltage ≤200mV at 1mA, SOT23-3 package compatibility, and absence of required external compensation capacitors.
Technical Context
The MAX6063BEUR 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 output capacitors, simplifying layout in space-constrained designs.
It operates across an input range of 3.2V to 12.6V, maintains regulation under sourcing (0–5mA) and sinking (–2mA to 0) loads, and exhibits 76dB PSRR at 120Hz. The device's 130ppm output hysteresis and 62ppm/1000hr long-term stability support precision metrology-grade applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6063AEUR-T | ±0.2% initial accuracy (vs. ±0.4% for MAX6063BEUR); otherwise identical specs and pinout | Required where factory calibration is impractical and tighter absolute accuracy is mandatory (e.g., calibrated test gear) | Select MAX6063AEUR-T when 0.2% tolerance justifies higher cost; MAX6063BEUR suffices for most industrial sensing |
| ADR3430ARJZ-R7 | ±0.1% initial accuracy, 10ppm/°C TC, but 120µA IQ and requires 1µF output cap for stability | Better accuracy/TC trade-off for lab-grade instruments; larger solution size due to capacitor requirement | Choose ADR3430ARJZ-R7 only if 0.1% accuracy outweighs board area penalty and higher quiescent current |
Compared with MAX6063AEUR-T, MAX6063BEUR offers lower cost and same thermal performance but relaxes initial tolerance by 0.2%; compared with ADR3430ARJZ-R7, it saves board area and reduces supply current by 30µA but trades 0.3% accuracy and 10ppm/°C TC for those advantages.

FAQ
What is the maximum input voltage rating for MAX6063BEUR?
The MAX6063BEUR 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., 3.2V to 12.6V for the 3.0V output. Operation above 12.6V is not characterized and may compromise long-term reliability or parametric guarantees.
Does MAX6063BEUR require an output capacitor for stability?
No, MAX6063BEUR does not require an external output capacitor for stability. Its internally compensated architecture 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.
What is the dropout voltage specification for MAX6063BEUR at full load?
The MAX6063BEUR specifies a maximum dropout voltage of 200mV at 1mA load current. At 5mA sourcing load, the dropout increases slightly but remains within 250mV - enabling reliable operation even as battery voltage declines to 3.25V in 3V systems.
How does the supply current of MAX6063BEUR vary with input voltage?
MAX6063BEUR exhibits only 3.4–8.0µA/V variation in supply current across its 3.2V–12.6V input range. This near-constant 90µA typical quiescent current - independent of VIN - maximizes battery efficiency and simplifies power budgeting versus shunt references whose current scales linearly with input voltage.
Is MAX6063BEUR pin-compatible with other devices in the MAX6061–MAX6068 family?
Yes, all MAX6061–MAX6068 variants, including MAX6063BEUR, share identical SOT23-3 pinout (IN, OUT, GND) and package dimensions. This allows drop-in replacement across output voltages (1.25V to 5.0V) without PCB redesign - provided input voltage and load requirements are verified for the new voltage option.
