The REG103FA-2.5/500G3 is a low-dropout linear voltage regulator designed to provide a stable output of 2.5V at a maximum output current of 500mA. It features an ultra-low dropout voltage of 115mV at full load, which enhances efficiency in battery-powered applications. The device operates with a typical ground pin current of 1mA and drops to 0.5¬µA when disabled, making it suitable for power-sensitive applications. This regulator does not require an output capacitor for stability, simplifying design and reducing component costs. It offers fast transient response and low output noise, typically 33¬µVrms, which is beneficial for sensitive electronic devices. The REG103FA-2.5/500G3 includes built-in thermal protection and foldback current limiting to safeguard against overload conditions. It is available in a DDPAK/TO-263-5 package, making it suitable for surface-mount applications. The operating temperature range is specified from -40¬8C to +85¬8C, ensuring reliability in various environments.
