What are the key features of this LDO?

It features a 300mA output current, 38µA quiescent current, auto-discharge circuit, internal enable pull-down, and thermal/current-limit protection.

What is the purpose of the auto-discharge feature?

The auto-discharge circuit, activated when the device is disabled, helps discharge the output capacitor, ensuring the output voltage drops quickly.

Is the enable pin safe to leave floating?

Yes, the MIC5504 includes an internal pull-down resistor on the enable pin, allowing it to be left floating while ensuring the output remains disabled.

What are the sourcing risks for this component?

The component is widely available from major distributors like Mouser and LCSC, indicating low supply risk.

What is the pinout of MIC5504-3.3YM5-TR?
