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 0.5µA 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 33µVrms, 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°C to +85°C, ensuring reliability in various environments.
