1.4.1 TPS7N59

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 (-30dB 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 softstart capabilities to provide good system performance. The versatility, performance, and small footprint design makes 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.
