UCC283TD-5 Description

The UCC283TD-5 is a fixed-output linear voltage regulator designed by Texas Instruments. It is part of the Linear & Switching Voltage Regulators category and is known for its robust performance and reliability. This regulator is designed to provide a stable 5V output voltage with a maximum input voltage of 9V. It can deliver a continuous output current of up to 3A, making it suitable for a wide range of applications that require a stable power supply.

The UCC283TD-5 features a single regulator with a positive output configuration. It has a dropout voltage of 0.6V at a maximum load current of 3A, ensuring efficient power conversion even under heavy load conditions. The regulator operates with a quiescent current of 65 µ0A, which is relatively low, contributing to its energy efficiency.

This regulator is housed in a surface-mount package, specifically the DDPAK/TO263-3, which is known for its thermal efficiency and compact size. The UCC283TD-5 also includes several protection features such as over-current, over-temperature, reverse polarity, short circuit, and under-voltage lockout (UVLO) to ensure safe and reliable operation.
