The device output voltage is adjustable from 0.8 V to 5.15 V using an external resistor divider. The combination of low-noise (4.4 µVRMS), high- PSRR, and high output current capability makes the TPS7A53-Q1 ideal to power noise-sensitive components such as those found in high-speed communications, radar power, infotainment applications. The high performance of this device 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 5.0-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 (1% over load and temperature), remote sensing, excellent transient performance, and soft-start capabilities of the TPS7A53-Q1 provides optimal system performance. The versatility of the TPS7A53-Q1 makes the device a component of choice for many demanding applications.
