FAQ

How does the MCP1501 handle capacitive loads?

The device can drive up to 10 nF of capacitive load directly. For larger capacitors, a series resistor must be used to maintain stability.

What is the function of the SHDN pin?

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