6A, low-input-voltage, low-noise, high-accuracy low-dropout (LDO) voltage regulator

The TPS7A56 is a

low-noise (2.45µVRMS), ultra-low-dropout linear regulator

(LDO) capable of sourcing 6A with only 90mV of dropout,

independently of the output voltage. The device output voltage is

adjustable from 0.5V to 5V using a single external resistor. The

combination of low noise, high PSRR (36dB at 1MHz), and high

output-current capability makes the TPS7A56 designed for powering noise-sensitive

components. These components (such as RF amplifiers, radar sensors,

SERDES, and analog chipsets) are found in radar power,

communication, and imaging applications.

Digital loads requiring low-input, low-output

(LILO) voltage operation also benefit from exceptional accuracy,

remote sensing, transient performance, and soft-start capabilities

to provide best system performance. These loads include

application-specific integrated circuits (ASICs), field-programmable

gate arrays (FPGAs), and digital signal processors (DSPs). The

versatility, performance, and small footprint make this LDO an

excellent choice for high-current analog loadsand digital loads such

as serializer/deserializers (SerDes), FPGAs, and DSPs. High-current

analog loads include analog-to-digital converters (ADCs),

digital-to-analog converters (DACs), and imaging sensors.
