Overview
The MCP1501T-30E/SN is a buffered voltage reference from the MCP1501 series, manufactured by Microchip Technology. It provides a fixed output voltage of 3.0 V with an initial accuracy of ±0.1%. The device operates within a supply voltage range of 3.2 V to 5.5 V and features a maximum temperature coefficient of 50 ppm/°C across the -40°C to +125°C operating temperature range. It is housed in an 8-Lead SOIC package and supports a maximum load current of ±20 mA.
Feature Summary
- Utilizes a low-drift band gap architecture with chopper-based amplifiers to minimize drift and offset errors.
- Capable of sourcing and sinking up to 20 mA of output current for robust load driving.
- Includes a dedicated shutdown pin (SHDN) for active low digital control of power consumption.
Applications
- Precision data acquisition systems
- High-resolution data converters
- Medical equipment applications
Procurement Notes
Verify the specific suffix 'SN' corresponds to the 8-Lead SOIC package configuration. Confirm that the 'T' designation indicates tape and reel packaging if required for automated assembly processes. Ensure the input supply voltage meets the minimum requirement of 3.2 V for proper regulation at the 3.0 V output level.
Selection Notes
Select this component when a stable 3.0 V reference is needed with high precision and moderate drive capability. Consider the 8-Lead SOIC package for through-hole or standard surface mount compatibility. Evaluate the 50 ppm/°C temperature coefficient against system thermal requirements to ensure long-term stability.
Part Context
This part belongs to the MCP1501 family of high-precision buffered voltage references. The family offers multiple voltage variants ranging from 1.024 V to 5.000 V. The MCP1501T-30E/SN specifically targets applications requiring a 3.0 V reference with tight tolerance specifications.
Replacement Considerations
Direct substitutes include other MCP1501 variants with different output voltages such as MCP1501-25E/SN or MCP1501-33E/SN, provided the voltage difference is acceptable for the circuit design.
