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 Package Types MCP1501 6-Lead SOT-23 OUT 1 GND 2 GND 3 6 VDD 5 GND 4 SHDN MCP1501 8-Lead SOIC VDD 1 NC 2 SHDN 3 GND 4 8 FEEDBACK 7 OUT 6 GND 5 GND MCP1501 2x2 WDFN* VDD 1 8 FEEDBACK GND 2 EP 7 OUT SHDN 3 9 6 GND GND 4 5 GND *Includes Exposed Thermal Pad (EP).
