Company Profile

Texas Instruments TPS75933KTTR 7.5A LDO Voltage Regulator 3.3V

TPS75933KTTR is a 7.5A, ultra-low dropout (LDO) linear voltage regulator from Texas Instruments (TI)

It's designed to provide a fixed 3.3V output from an input voltage range of 2.8V to 5.5V.

A key advantage of this LDO is its very low dropout voltage—typically 400mV at the full 7.5A load—which means it can regulate the output voltage even when the input voltage is only slightly above the output level, making it highly efficient for powering modern low-voltage circuits.

Typical Applications:

This high-current, low-dropout regulator is commonly used in various electronic systems where stable and clean power is critical for high-current loads:

Server & Networking Equipment: Powering high-performance CPUs, FPGAs, , and memory modules on server motherboards, network routers, and switches, especially where point-of-load regulation is needed.
Industrial Automation & Control Systems: Providing reliable power to sensors, motor controllers, and PLCs (Programmable Logic Controllers) in harsh industrial environments (note its wide operating temperature range of -40°C to +125°C).
Automotive Electronics: While not explicitly stated as automotive-grade in the search results, its wide temperature range and robust protection features make it a potential candidate for infotainment systems, advanced driver-assistance systems (ADAS), or body control modules.
Telecommunications Infrastructure: Used in base stations and other comms gear to regulate power for RF power amplifiers and signal processing circuits.
High-Power Consumer Electronics: Could be found in gaming consoles, high-end displays, or other devices requiring a high-current, low-noise 3.3V rail.
