Texas Instruments REG103FA-3-3-500 is a positive fixed output linear voltage regulator IC. This component offers a stable 3.3V output with a maximum output current of 500mA. Designed for surface mount applications, it is supplied in a TO-263 (DDPAK-5) package, delivered on tape and reel. Key features include an enable pin for control, quiescent current of 0.7mA, and a maximum input voltage of 15V. The device provides robust protection against over-current and over-temperature conditions. With a specified dropout voltage of 0.28V at 500mA and a Power Supply Rejection Ratio (PSRR) of 65dB at 120Hz, the REG103FA-3-3-500 is suitable for applications requiring efficient and stable power regulation, such as in industrial controls and automotive systems. The operating temperature range is -40°C to 85°C.
