The TPS7A4701-EP is a positive voltage (36 V), ultra-low-noise (4 µVRMS) low-dropout linear regulators (LDO) capable of sourcing a 1-A load.

The TPS7A4701-EP output voltage can be configured with a user-programmable PCB layout (up to 20.5 V), or adjustable (up to 34 V) with external feedback resistors.

The TPS7A4701-EP 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 critical applications such as medical, radio frequency (RF), and test-and-measurement.

In addition, the TPS7A4701-EP 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, test-and-measurement, audio, and RF applications.
