3 Description
The TPS7A4701-EP is a positive voltage (36 V),
ultra-low-noise (4 µV_RMS) 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.
