TPS7A83A

SBVS304B – JUNE 2017 – REVISED OCTOBER 2021

TPS7A83A 2-A, High-Accuracy (0.75%), Low-Noise (4.4 μV_RMS) LDO Regulator

1 Features

3 Description

•

Low dropout: 200 mV (max) at 2 A

Accuracy over line, load, and temperature with

BIAS: 0.75% (max)

Output voltage noise:

– 4.4 μV_RMSat 0.8-V output

Input voltage range:

– Without BIAS: 1.4 V to 6.5 V

– With BIAS: 1.1 V to 6.5 V

TPS7A8300A output voltage range:

– Adjustable operation: 0.8 V to 5.2 V

– ANY-OUT^™operation: 0.8 V to 3.95 V

TPS7A8301A output voltage range:

– Adjustable operation: 0.5 V to 5.2 V

– ANY-OUT^™operation: 0.5 V to 2.075 V

Power-supply ripple rejection:

– 40 dB at 500 kHz

The TPS7A83A is a low-noise (4.4 μV_RMS), low-

dropout, 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 noise-

sensitive components such as those found in high-

speed 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.

•

Excellent load transient response

Adjustable soft-start inrush control

Open-drain power-good (PG) output

2 Applications

•

Macro remote radio units (RRU)

Outdoor backhaul units

Active antenna system mMIMO (AAS)

Ultrasound scanners

Lab and field instrumentation

Sensor, imaging, and radar
