Overview
The MAX6066BEUR+T is a precision, micropower, low-dropout voltage reference featuring a fixed 2.5V output in a 3-pin SOT-23 package. It delivers an initial accuracy of ±0.4% and a maximum temperature coefficient of 30ppm/°C across the -40°C to +85°C range. The device typically draws 90µA of supply current, supports sourcing up to 5mA or sinking 2mA, and operates with an input voltage range from VOUT + 0.2V to 12.6V.
Feature Summary
- Proprietary curvature-correction circuitry ensures high precision and stability
- Laser-trimmed thin-film resistors provide tight initial accuracy specifications
- Internally compensated design eliminates the need for external compensation capacitors
- Supply current remains virtually independent of the input voltage level
Applications
- Analog-to-Digital Converters (ADCs)
- Portable Battery-Powered Systems
- Precision 3V/5V Systems
Procurement Notes
Verify the specific suffix 'B' indicates the ±0.4% accuracy grade rather than the tighter ±0.2% variant. Confirm the '+T' designation corresponds to tape-and-reel packaging requirements. Ensure the ordering increment aligns with manufacturer standards for SOT-23 packages. Cross-reference the datasheet revision to confirm pinout consistency.
Selection Notes
Select this component when board space is limited due to the compact SOT-23 form factor. Choose this part if the application requires a fixed 2.5V reference without external trimming. Consider the quiescent current consumption against battery life requirements. Verify that the load current does not exceed the specified sourcing or sinking limits.
Part Context
This device belongs to the MAX6061–MAX6068 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common internal architecture but varies in output voltage options ranging from 1.25V to 5V. The MAX6066 specifically provides the 2.5V option within this series.
Replacement Considerations
Other members of the MAX6061–MAX6068 family share identical pinouts and functionality but offer different fixed output voltages. Substitution is possible only if the system design accommodates the alternative voltage level.
