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

What is the minimum capacitance required for stable operation?

The device requires a minimum of 1µF ceramic capacitor on both the input and output pins to ensure stability and proper transient response.

How does the enable pin function?

The EN pin is active-high; setting it to a logic high level turns the regulator on, while pulling it low disables the output.
