Description for the TPS7A53-Q1

The TPS7A53-Q1 device is a low-noise (4.4 µVRMS), low-dropoutlinear regulator (LDO) capable of sourcing 3 A with only 180 mV of maximum dropout.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 highoutput current capability makes the TPS7A53-Q1 an excellent choice to power noise-sensitivecomponents, such as those found in radar power and infotainment applications. The high performanceof this device limits power-supply-generated phase noise and clock jitter, making this device anexcellent choice for powering RF amplifiers, radar sensors, and chipsets. Specifically, RFamplifiers 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) that requirelow-input, low-output (LILO) voltage operation, the exceptional accuracy (1% over load andtemperature), remote sensing, excellent transient performance, and soft-start capabilities of theTPS7A53-Q1 provide optimal system performance.

The versatility of the TPS7A53-Q1 makes the device a component of choice for manydemanding applications.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
