3 Description
The TPS7A57 is a low-noise (2.45 μVRMS), ultra-lowdropout
linear regulator (LDO) capable of sourcing
5 A with only 75 mV of dropout, independently
of the output voltage. The device output voltage
is adjustable from 0.5 V to 5.2 V using a single
external resistor. The combination of low noise,
high PSRR (36 dB at 1 MHz), and high outputcurrent
capability makes the TPS7A57 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 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-todigital
converters (ADCs), digital-to-analog converters
(DACs), and imaging sensors as well as digital loads
such as serializer/deserializers (SerDes), FPGAs, and
DSPs.
