Product details
Overview
MAX6063BEUR-T from Maxim Integrated is a precision, low-dropout, micropower 3.0V series voltage reference in a 3-pin SOT23 package. It delivers ±0.4% initial accuracy, 20ppm/°C (max) temperature coefficient, and supports 5mA sourcing / 2mA sinking load current. Designed for high-accuracy analog signal chains in space-constrained battery-powered systems, it operates from (VOUT + 0.2V) to 12.6V input and draws only 90µA typical supply current.
For engineers reviewing the MAX6063BEUR-T datasheet, MAX6063BEUR-T pinout, MAX6063BEUR-T application, or MAX6063BEUR-T equivalent, key selection criteria include its 3.0V output stability over -40°C to +85°C, ultra-low quiescent current independent of input voltage, absence of required external compensation capacitor, and compatibility with capacitive loads up to 1µF without oscillation.
Technical Context
The MAX6063BEUR-T is a three-terminal series-mode voltage reference employing proprietary curvature-correction circuitry and laser-trimmed thin-film resistors. Its internal compensation eliminates need for external output capacitance, while BiCMOS process enables stable operation with capacitive loads and low dropout (200mV max at 1mA).
It features supply-current independence (≤8µA/V variation), 76dB power-supply rejection at 120Hz, and 35µVp-p (0.1Hz–10Hz) output noise. The device maintains specified performance across its full input range (3.2V to 12.6V) and load range (±2mA sink/source), making it suitable for precision ADC biasing and portable system references where board area and power efficiency are critical.

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% initial accuracy, 50ppm/°C TC, 50µA IQ, SOT23-3 | Lower accuracy but lower quiescent current; higher TC limits use in wide-temp industrial apps | Select for ultra-low-power (<50µA) designs where ±0.2% accuracy suffices and temp range is limited |
| ADR3430ARJZ-R7 | 3.0V, ±0.1% initial accuracy, 10ppm/°C TC, 120µA IQ, SOT23-3 | Higher accuracy and lower TC, but 33% higher supply current and requires 1µF output cap | Select when sub-10ppm/°C stability is mandatory (e.g., metrology) and board space allows output capacitor |

FAQ
What is the maximum input voltage for MAX6063BEUR-T?
The MAX6063BEUR-T supports an input voltage range from (VOUT + 0.2V) = 3.2V up to 12.6V. Absolute maximum rating is +13.5V on the IN pin. Operation above 12.6V is not guaranteed and may degrade long-term reliability or violate absolute maximum ratings.
Does MAX6063BEUR-T require an external output capacitor?
No, MAX6063BEUR-T does not require an external output capacitor due to internal compensation. It remains stable with 0–1µF capacitive loads. Adding a 0.1µF ceramic capacitor is optional and improves transient response in high-step-load applications but is unnecessary for basic stability.
What is the load current capability of MAX6063BEUR-T?
MAX6063BEUR-T can source up to 5mA and sink up to 2mA while maintaining output regulation within specifications. Load regulation is specified as 0.5–6.0mV/mA depending on direction and current level, ensuring minimal voltage shift under dynamic load conditions.
How does the temperature coefficient of MAX6063BEUR-T affect system accuracy?
With a maximum temperature coefficient of 20ppm/°C, MAX6063BEUR-T contributes ≤±0.6mV drift over its full -40°C to +85°C operating range. This translates to <±0.02% error in a 3.0V reference-sufficient for 12–14 bit system accuracy without active calibration.
Is MAX6063BEUR-T pin-compatible with other devices in the MAX6061–MAX6068 family?
Yes, all MAX6061–MAX6068 variants-including MAX6063BEUR-T-share identical 3-pin SOT23-3 pinout (IN, OUT, GND) and package dimensions. This allows drop-in replacement across output voltages (1.25V to 5.0V) without PCB layout changes, provided input voltage and load requirements are met.
