Introduction
The MCP1501 is a buffered voltage reference capable of sinking and sourcing 20 mA of current. The voltage reference is a low-drift bandgap-based reference. The bandgap uses chopper-based amplifiers, effectively reducing the drift to zero.
The MCP1501 is available in the following packages:
6-Lead SOT-23 8-Lead SOIC 8-Lead 2 mm x 2 mm WDFN
