Texas Instruments' TPS7A47 is a positive voltage (+36 V), gain-independent, ultra-low noise (3.5 µVRMS) linear regulator capable of sourcing a maximum 1 A load. In contrast with other voltage regulators, which amplify intrinsic noise as a function of output voltage, the TPS7A47 maintains a constant intrinsic noise level constant throughout the output voltage range from 1.4 V to 19.1 V. In addition, the TPS7A47 output voltage is fully user-adjustable via the printed circuit board (PCB) layout without the need of external resistors, thus reducing overall component count. The TPS7A47 is designed with bipolar technology, primarily for high-accuracy, high-precision instrumentation applications where clean voltage rails are critical to maximize system performance.
