Description

The TPS7A52 is a low-noise (4.4 µVRMS), ultra-low dropout linear regulator (LDO) capable of sourcing 2 A with only 65 mV of maximum dropout. The device output voltage is adjustable 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 TPS7A52 an excellent choice to power noise-sensitive components such as those found in high-speed communications, video, medical, or test-and-measurement 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), and digital-to-analog converters (DACs). Specifically, RF amplifiers benefit from the high performance and 5.2-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 (0.5% over load and temperature), remote sensing, excellent transient performance, and soft-start capabilities of the TPS7A52 provides optimal system performance. As an adjustable voltage regulator, there is versatility in the design of the TPS7A52 that makes the device a component of choice for analog loads such as voltage-controlled oscillator (VCO), ADC, DAC, and imaging sensors and for digital loads such as SerDes, FPGAs, and DSPs.
