Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ
What is the function of the third pin on the SOT23 package?
The third pin serves as the Enable (EN) input, allowing the user to turn the regulator output on or off using a logic signal.
Does the AP7375-18SA-7 require external capacitors for stability?
Yes, a minimum output capacitor of 1µF is required for stability, and a 1µF input capacitor is recommended for decoupling.
