Overview
The MAX6330SUR is a precision shunt voltage reference integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 3 V with an initial accuracy of 1.5% and a temperature coefficient of 40 PPM/°C. The device supports a maximum shunt current of 50 mA and operates within a temperature range of -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount format, it is designed for applications requiring stable voltage regulation in space-constrained environments.
Feature Summary
- Integrates precision shunt voltage reference functionality with reset capabilities
- Delivers stable 3 V output with high initial accuracy
- Operates reliably across extended industrial temperature ranges
Applications
- Battery-powered portable electronic devices
- Precision measurement instrumentation systems
- Microprocessor supervisory circuits
Procurement Notes
Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm RoHS compliance status as indicated in official documentation. Check for end-of-life notices or obsolescence warnings prior to procurement. Ensure packaging specifications match design requirements for surface-mount assembly processes.
Selection Notes
Evaluate thermal management requirements based on the 50 mA maximum shunt current capability. Verify that the 1.5% initial accuracy meets system tolerance specifications. Consider the SOT-23-3 package dimensions for PCB layout constraints. Assess compatibility with existing voltage reference architectures in the target application design.
Part Context
This component belongs to the MAX6330 series of precision shunt regulators. It represents Maxim Integrated's approach to combining voltage referencing with supervisory functions in minimal footprint packages. The series targets low-power applications where size and stability are critical design parameters.
Replacement Considerations
Consult official datasheets for pin-compatible alternatives within the MAX633x family. Verify electrical parameter equivalence before substitution. Cross-reference package dimensions and thermal characteristics. No direct substitute part numbers are confirmed in available public documentation.
