DESCRIPTION

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

· It features a user-programmable PCB layout for output voltage configuration up to 20.5V or adjustable up to 34V with external feedback resistors.

· Designed with bipolar technology, it is ideal for high-accuracy, high-precision instrumentation applications.

· It is suitable for powering operational amplifiers, ADCs, DACs, and other high-performance analog circuitry in medical, RF, and test-and-measurement applications.

· It is also ideal for post DC-DC converter regulation, filtering out output voltage ripple to ensure maximum system performance.
