The TPS7N59 is a low-noise (2.5µVRMS), ultra-low-dropout linear regulator (LDO) capable of sourcing 10A with only 150mV of dropout, independently of the output voltage. The device output voltage is adjustable from 0.5V to 5.2V using a single external resistor. The combination of low noise, high PSRR (30 dB at 1MHz), and high output-current capability makes the TPS7N59 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 good 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 serializer/deserializers (SerDes), FPGAs, and DSPs.
