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.
