The device output voltage is pin-programmable from 0.8 V to 3.95 V and adjustable from 0.8 V to 5.0 V using an external resistor divider. The bination of low-noise (4.4 µVRMS), high PSRR, and high output current capability makes the TPS7A84 ideal to power noise-sensitive ponents such as those found in high-speed munications, video, medical, or test and measurement applications. The high performance of the TPS7A84 limits power-supply-generated phase noise and clock jitter, making this device ideal for powering highperformance serializer and deserializer (Ser Des), analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and RF ponents. Specifically, RF amplifiers benefit from the high-performance and 5.0-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 load and temperature), remote sensing, excellent transient performance, and soft-start capabilities of the TPS7A84 ensure optimal system performance. - Digital Loads: Ser Des,...
