Supply and Recall (TI) TPS7A5310AQWRTJRQ1 3A, high precision automotive grade low noise LDO regulator.

Device description:

The TPS7A5310AQWRTJRQ1 is a low-noise (5.6µVRMS), low-drop linear regulator (LDO) that delivers 3A pull current with a voltage drop of only 130mV. The TPS7A53A-Q1 combines low noise (5.6µVRMS), high PSRR, and high output current capability to power noise-sensitive components in applications such as radar power and infotainment. The excellent performance of this device inhibits phase noise and clock jitter from power supplies, making it suitable for powering RF amplifiers, radar sensors and chipsets. Specifically, the signal chain component will benefit from the high performance of the device. The TPS7A53A-Q1 also offers a wet-side option for easy optical inspection.

For digital loads that need to operate at low input and low output (LILO) voltages, such as application-specific integrated circuits (ASics), field programmable gate arrays (FPgas), and digital signal processors (DSPS), The excellent accuracy of the TPS7A53AQ1 (up to 1.3% across load and temperature ranges), remote sensing, excellent transient performance and soft start enable excellent system performance.
