1. Describe

The TPS7A5201QRGRRQ1 device is a low noise (4.4µVRMS), low dropout linear regulator (LDO) capable of delivering 2 A with a maximum dropout of only 115 mV. The device's output voltage can be used from 0.8 V to 5.2 V using an external resistor divider. The combination of low noise (4.4 µVRMS), high PSRR, and high output current capability makes the TPS7A5201QRGRRQ1 ideal for noise-sensitive power supplies such as those found in radar power supplies and infotainment applications. The high performance of the device limits phase noise and clock jitter from the power supply, making the device ideal for powering RF amplifiers, radar sensors and chipsets. Specifically, RF amplifiers benefit from high performance and 5.0-V output capable devices. 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, excellent accuracy (over 1% load and temperature), remote sensing, excellent transient performance and soft-start capability TPS7A52-Q1 provides the best system Performance. The versatility of the TPS7A52-Q1 makes this device a preferred component for many demanding applications.
