MCP1501T-33E/CHYVAO

Overview

The MCP1501T-33E/CHYVAO is a buffered voltage reference with a fixed output of 3.3V, housed in a 6-lead SOT-23 package. It features an initial accuracy of 0.1% and a maximum temperature coefficient of 50 ppm/°C across the -40°C to +125°C operating range. The device supports a supply voltage from 3.5V to 5.5V, draws a typical current of 140 μA, and can source or sink up to 20 mA. It includes a shutdown pin and is AEC-Q100 qualified.

Feature Summary

• Chopper-based amplifier architecture reduces drift and offset for high precision
• Capable of sourcing and sinking 20 mA load current
• Includes active low digital shutdown control pin
• Automotive qualified under AEC-Q100 standards

Applications

• Precision data acquisition systems
