Automotive, 3-A, low-VIN 5.6-µVRMS low-noise high-accuracy ultra-low dropout voltage regulator

The TPS7A53A-Q1 is a low-noise (5.6

µVRMS), low-dropout linear regulator (LDO) capable of sourcing 3 A

with only 130 mV of dropout.

The combination of low noise (5.6

µVRMS), high PSRR, and high output current capability makes the

TPS7A53A-Q1 designed for powering noise-sensitive components, such as those found in

radar power and infotainment applications. The high performance of this device

limits power-supply-generated phase noise and clock jitter, making this device

useful for powering RF amplifiers, radar sensors, and chipsets. Specifically, signal

chain components benefit from the high-performance of the device. The TPS7A53A-Q1 is

available with a wettable flanks option to facilitate optical inspection.

For digital loads [such as

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

(FPGAs), and digital signal processors (DSPs)] that require low-input, low-output

(LILO) voltage operation, the exceptional accuracy (1.3% over load and temperature),

remote sensing, excellent transient performance, and soft-start capabilities of the

TPS7A53A-Q1 provide optimal system performance.

The versatility of the TPS7A53A-Q1

makes the device a component of choice for many demanding applications.
