TPS7A8400ARGRR

The TPS7A84A is a low-noise, low-dropout linear regulator (LDO) capable of sourcing 3 A with only 180 mV of maximum dropout. The device output voltage is pin-programmable from 0.8 V to 3.95 V and adjustable from 0.8 V to 5.15 V using an external resistor divider. The combination of low-noise, high-PSRR, and high output-current capability makes the TPS7A84A ideal to power noise-sensitive components such as those found in high-speed communications, video, medical, or test and measurement applications. The high performance of the TPS7A84A limits power-supply-generated phase noise and clock jitter, making this device ideal for powering high-performance serializer and deserializer (SerDes), analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and RF components. Specifically, RF amplifiers benefit from the high-performance and >5 - V output capability of the device. For digital loads [such as application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), and digital signal processors (DSPs)] requiring low-input voltage, low-output (LILO) voltage operation, the exceptional accuracy (0.75% over line, load, and temperature), remote sensing, excellent transient performance, and soft-start capabilities of the TPS7A84A ensure optimal system performance. The versatility of the TPS7A84A makes the device a component of choice for many demanding applications.
