TPS75533KTTT  

Linear & Switching Voltage Regulators

TPS75533KTTT Description

The TPS75533KTTT is a linear voltage regulator designed by Texas Instruments, offering a fixed output voltage of 3.3V with a maximum input voltage of 5.5V. This regulator is capable of delivering up to 5A of output current, making it suitable for applications requiring high current. The device features a single regulator with a positive output configuration and a dropout voltage of only 0.5V at 5A, ensuring efficient operation even at high loads. Despite its high performance, the TPS75533KTTT maintains a low quiescent current of 200 µA, contributing to energy efficiency. It also includes control features such as enable and power good, as well as protection features like over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The is regulator packaged in a surface-mount DDPAK/TO263-5 format, making it ideal for compact designs. However, it should be noted that the TPS75533KTTT is currently in an obsolete product status, though it remains RoHS3 compliant and REACH unaffected.
