The Texas Instruments REG103GA-3.3/2K5G4 is a linear voltage regulator from the REG103 family, designed for low-noise and low-dropout applications. It features a fixed 3.3V output voltage and can supply up to 500mA of current. The device boasts a low dropout voltage of 115mV typical at 500mA and requires no external output capacitor for stability, simplifying circuit design.
Key electrical characteristics include a wide input voltage range from 2.7V to 15V, a typical quiescent current of 1mA at 500mA output, and a low noise level of 33µVrms. It also offers protection features such as over current and over temperature protection, along with an enable control feature.
Packaged in a compact SOT-223-6 surface-mount package, the REG103GA-3.3/2K5G4 operates within an ambient temperature range of -40°C to 85°C. Its high PSRR of 65dB at 120Hz makes it suitable for power-sensitive applications where clean power is essential.
