FAQ

How does the MCP1501 handle capacitive loads?

The device can drive up to 10nF 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 a digital input that places the device into a low-power shutdown mode when driven low, effectively disabling the output.
