3 Description

linear regulator (LDO) capable of sourcing 2 A with

only 125 mV of maximum dropout. The device output

voltage is pin-programmable from 0.8 V to 3.95 V and

adjustable from 0.8 V to 5.2 V using an external

resistor divider.

PSRR, and high output current capability makes the

TPS7A52 an excellent choice to power noise-

sensitive components such as those found in high-

speed communications, video, medical, or test-and-

measurement applications. The high performance of

this

device

limits

power-supply-generated

phase

noise and clock jitter, making this device ideal for

powering high-performance serializer and deserializer

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

digital-to-analog converters (DACs). Specifically, RF

amplifiers benefit from the high performance and 5.2-

V output capability of the device.

For

digital

loads

[such

as

application-specific

integrated circuits (ASICs), field-programmable gate

arrays

(FPGAs),

and

digital

signal

processors

(DSPs)] requiring low-input voltage, low-output (LILO)

voltage operation, the exceptional accuracy (0.75%

over

load

and

temperature),

remote

sensing,

excellent

transient

performance,

and

soft-start

capabilities of the TPS7A52 provides optimal system

performance.

As an adjustable voltage regulator, there is versatility

in the design of the TPS7A52 that makes the device

a component of choice for analog loads such as

voltage-controlled oscillator (VCO), ADC, DAC, and

imaging sensors and for digital loads such as

SerDes, FPGAs, and DSPs.
