Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the minimum output capacitor required for stability?

The MIC47050 requires a minimum of 1μF ceramic output capacitor for stability.

How does the enable pin function?

The enable pin is active-high. A logic-high signal enables the regulator, while a logic-low signal shuts it down, reducing ground current to near zero.
