3 Description

The TPS7A83A is a low-noise (4.4 μVRMS), lowdropout,

linear regulator (LDO) capable of sourcing

2 A with only 200 mV of maximum dropout. The

TPS7A8300A output voltage is pin programmable

from 0.8 V to 3.95 V with a 50-mV resolution, and

adjustable from 0.8 V to 5.2 V using an external

resistor divider. The TPS7A8301A output voltage is

pin programmable from 0.5 V to 2.075 V with a 25-mV

resolution, and adjustable from 0.5 V to 5.2 V using

an external resistor divider.

The combination of low noise , high PSRR,

and high output current capability makes the

TPS7A83A an excellent choice to power noisesensitive

components such as those found in highspeed

communications, video, medical, or test

and measurement applications. This device is

designed for powering high-performance serializer

and deserializer (SerDes), analog-to-digital converters

(ADCs), digital-to-analog converters (DACs), and

RF components because the high performance of

the TPS7A83A limits power-supply-generated phase

noise and clock jitter. Specifically, RF amplifiers

benefit from the high-performance and 5.2-V output

capability of the device.
