The TPS7A4001DGNR is a Low Dropout (LDO) Linear Voltage Regulator from Texas Instruments that is designed to provide a stable, accurate voltage output for many types of applications. It is a single-output device which provides 50mA of current, support for an input voltage up to 100V, and all of the features expected of a regulator from TI, such as short-circuit protection, thermal shutdown, and reverse-battery protection. It also has logic enable/disable control, and is optimized for low power consumption to allow for up to 97% efficiency in idle or low output current loads. The TPS7A4001 is specifically designed for portable consumer, automotive, and industrial applications, providing a high-accuracy output, low output noise, and excellent overall performance.
