Texas Instruments TPS7A4700 Low Noise, 1A Low-Dropout Linear Regulator

Texas Instruments TPS7A4700 Low Noise, 1A Low-Dropout Linear Regulator is a positive voltage (+36V), ultralow-noise (4.17µVRMS) linear regulator capable of sourcing a 1A load. TI TPS7A4700 has an output voltage that is fully user-adjustable via a printed circuit board (PCB) layout without the need of external resistors or feed-forward capacitors, thus reducing overall component count. TI TPS7A4700 LDO is designed with bipolar technology, primarily for high-accuracy, high-precision instrumentation applications where clean voltage rails are critical to maximize system performance. This TI device is ideal for powering operational amplifiers, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other high-performance analog circuitry in critical applications (such as medical, RF, and test-and-measurement).

TPS7A4700EVM-094 Evaluation Module is designed to help engineers evaluate the operation and performance of the TPS7A4700 linear regulator for possible use in their own circuit application.
