The Texas Instruments LP38843T-1-2 is a high-performance, 1.2V fixed output linear voltage regulator with a robust 3A current capability. This device is engineered for demanding applications, offering superior performance with a typical quiescent current of 30 µA. Its exceptional Power Supply Rejection Ratio (PSRR) of 80dB to 65dB across the 120Hz to 1kHz range ensures stable output voltage even with noisy input sources. The LP38843T-1-2 features comprehensive protection circuitry, including over-current, over-temperature, and short-circuit protection. Designed for through-hole mounting in a TO-220-5 package, this regulator is suited for use in telecommunications, industrial automation, and automotive systems. The low dropout voltage of 0.5V at 3A further enhances its efficiency in power-sensitive designs.
