General Description

The MCP1501 is a buffered voltage reference capable

of sinking and sourcing 20 mA of current. The voltage

reference is a low-drift band gap based reference. The

band gap uses chopper-based amplifiers, effectively

reducing the drift to zero.

The MCP1501 is available in the following packages:

• 6-Lead SOT-23
