Additional Details:

The AP1115BY25L is designed to operate with a low dropout voltage, allowing it to maintain a stable output voltage even when the input voltage is close to the output voltage. The low quiescent current minimizes power consumption, extending battery life in portable applications. The over-current protection limits the output current in the event of a short circuit or overload, protecting the regulator and downstream components. The thermal shutdown protection disables the regulator when the junction temperature exceeds a safe limit. The regulator is stable with ceramic output capacitors, which offer low ESR and excellent transient response. Package type is typically SOT-223.
