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

What is the function of the EN pin on the AP7365?

The EN pin serves as an active-high enable input. Setting this pin to a logic high level turns the regulator on, while pulling it low disables the output.

How does the AP7365 protect against overcurrent conditions?

The device includes built-in current limit and short circuit protection. If the output current exceeds the threshold, the protection circuitry clamps the current to prevent damage to the regulator.
