1A, 36V low-noise high-PSRR low-dropout voltage regulator with enable

The TPS7A47 is a family of positive voltage

(+36V), ultralow-noise (4 µVRMS) low-dropout linear regulators (LDO)

capable of sourcing a 1A load.

The TPS7A4700 output voltages are

user-programmable (up to 20.5V) using a printed circuit board (PCB) layout without

the need of external resistors or feed-forward capacitors, thus reducing overall

component count.

The TPS7A4701 output voltage can be configured

with a user-programmable PCB layout (up to 20.5V), or adjustable (up to 34V) with

external feedback resistors.

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. 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 TPS7A47 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.

For

applications where positive and negative low-noise rails are required, consider TI’s

TPS7A33 family of negative high-voltage, ultralow-noise linear

regulators.
