MCP1501T-10E/RW

Overview

The MCP1501T-10E/RW is a buffered voltage reference from Microchip Technology, providing a fixed output of 1.024 V with an initial accuracy of ±0.1%. It operates within a supply voltage range of 1.65 V to 5.5 V and maintains a maximum temperature coefficient of 50 ppm/°C across the -40°C to +125°C operating range. The device features a typical operating current of 140 μA and can source or sink up to 20 mA. It is housed in an 8-WDFN (2x2 mm) package.

Feature Summary

• Utilizes a low-drift band gap architecture with chopper-based amplifiers to minimize drift and offset errors.
• Capable of sourcing and sinking 20 mA of load current for robust performance under varying loads.
• Includes a dedicated shutdown pin for digital control of power consumption.

Applications

• Precision data acquisition systems
• High-resolution data converters
• Medical equipment applications

Procurement Notes

Verify that the specific suffix 'RW' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the component meets RoHS compliance standards as specified by the manufacturer. Ensure the ordering part number matches the exact voltage variant and package type needed for the design.

Selection Notes

Select this component when a stable 1.024 V reference is required with high precision and low noise characteristics. Consider the 8-WDFN package for compact surface-mount designs where thermal dissipation and board space are critical constraints compared to larger packages.

Part Context

This part belongs to the MCP1501 series of high-precision buffered voltage references. The family offers multiple fixed voltage options ranging from 1.024 V to 5.000 V. While other variants may offer automotive qualification in different packages, this specific WDFN version provides industrial-grade performance in a small form factor.

Replacement Considerations

Direct substitutes include other MCP1501 variants such as MCP1501-12E/RW or MCP1501-33E/RW if the voltage level differs. For non-buffered requirements, consider the MCP1502 series, though functional differences exist.
