The TPS7A47 from Texas Instruments is a high-performance 1A low-dropout (LDO) linear regulator designed for precision analog, RF, medical, and test & measurement applications. With ultra-low output noise and excellent PSRR performance, the TPS7A47 is widely used in sensitive power supply designs requiring clean and stable voltage rails.

　　The device supports up to 36V input voltage and delivers extremely low output noise of only 4µVRMS, making it ideal for powering ADCs, DACs, PLLs, operational amplifiers, RF modules, and high-speed data converters.

　　Key Features

　　·Wide input voltage range: 3V to 36V

　　·Output current up to 1A

　　·Ultra-low noise: 4µVRMS (10Hz to 100kHz)

　　·High PSRR:

　　     ·82dB at 100Hz

　　     ·55dB across wide frequency range

　　·Low dropout voltage: 307mV at 1A

　　·Adjustable and fixed output versions

　　·Enable pin and soft-start support

　　·Thermal shutdown and current limit protection

　　·Compact 5mm × 5mm QFN package

　　·Operating temperature: -40°C to +125°C

　　Main Applications

　　The TPS7A47 is optimized for ultra-clean analog power rails in:

　　·RF and microwave systems

　　·Medical instrumentation

　　·Audio equipment

　　·Precision measurement equipment

　　·ADC/DAC power supplies

　　·FPGA and clock circuits

　　·Post-regulation after DC/DC converters

　　Its high PSRR performance effectively suppresses switching noise from upstream DC/DC converters, improving overall system signal integrity.
