MCP1501T-30E/RW

Overview

The MCP1501T-30E/RW is a buffered voltage reference IC from Microchip Technology, featuring a fixed 3.000V output with an initial accuracy of ±0.1%. It operates within a supply voltage range of 3.2V to 5.5V and delivers up to 20mA of load current. The device utilizes a low-drift bandgap architecture with chopper-based amplifiers to minimize temperature drift, achieving a maximum temperature coefficient of 50 ppm/°C across the -40°C to +125°C operating range.

Feature Summary

• Chopper-based amplifier architecture effectively reduces temperature-dependent offsets and long-term drift.
• Capable of sourcing and sinking up to 20mA of output current for high-drive applications.
• Includes a dedicated digital shutdown pin for active power management control.

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converters
• Industrial control circuits

Procurement Notes

Verify the specific suffix 'RW' against official documentation to confirm the 8-WDFN package type. Ensure the input voltage meets the minimum requirement of 3.2V for stable operation at the 3.0V output level. Confirm RoHS compliance status prior to integration.

Selection Notes

Select this component when a precise 3.0V reference is required in a compact surface-mount footprint. The WDFN package offers thermal advantages over larger alternatives. Consider the 140µA typical supply current for battery-powered designs requiring efficient power usage.

FAQ

How does the MCP1501 achieve its low temperature coefficient?

It uses a second-order temperature compensated bandgap circuit combined with chopper-based amplifiers to eliminate offset drift.

What is the function of the SHDN pin?

The SHDN pin is a digital input that places the device into a low-power shutdown state when driven low, disabling the output.
