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

What is the function of the third pin on the SOT23 package?

The third pin is the Enable (EN) pin, which accepts an input voltage up to 45V to turn the LDO output on or off.

Does the AP7375-50SA-7 require external components for stability?

Yes, a minimum output capacitance of 1µF is required for stability, and a 1µF input capacitor is recommended for decoupling.
