TPS7A4701QRGWRQ1 General Description

The TPS7A47-Q1 device is a positive voltage (35 V), ultra-low-noise (4.2 μVRMS) low-dropout linear regulator (LDO) capable of sourcing a 1-A load.

The TPS7A47-Q1 output voltage can be configured with a user-programmable printed circuit board (PCB) layout (up to 20.5 V), or adjustable (up to 34 V) with external feedback resistors.

The TPS7A47-Q1 is designed with bipolar technology primarily for high-accuracy, high-precision instrumentation applications where clean voltage rails are critical to maximize system performance. This feature makes the device ideal for powering operational amplifiers, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other high-performance analog circuitry.

In addition, the TPS7A47-Q1 is ideal for post dc-dc converter regulation. By filtering out the output voltage ripple inherent to dc-dc switching conversions, maximum system performance is ensured in sensitive instrumentation, audio, and RF applications.
