3A high-PSRR ultra-low-dropout linear regulator

The TPS7N53 is a

low-noise (2.2µVRMS), ultra-low-dropout linear regulator

(LDO) capable of sourcing 3A with only 95mV of dropout (typ),

independently of the output voltage. The device output voltage is

adjustable from 0.5V to 1.5V using a single external resistor. The

combination of low noise, high PSRR, and high output-current

capability makes the TPS7N53 designed

for powering noise-sensitive components (such as RF amplifiers,

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

communication, and imaging applications.

Digital loads [such as application-specific

integrated circuits (ASICs), field-programmable gate arrays (FPGAs),

and digital signal processors (DSPs)] requiring low-input,

low-output (LILO) voltage operation also benefit from the

exceptional accuracy (1.5% over load, line, and temperature), remote

sensing, excellent transient performance, and soft-start

capabilities to provide optimal system performance. The versatility,

performance, and small footprint solution make this LDO an excellent

choice for high-current analog loads such as analog-to-digital

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

sensors as well as digital loads such as serializers/deserializers

(SerDes), FPGAs, and DSPs.
