UCC383TDKTTT-5

UCC383TDKTTT-5 Description

The UCC383TDKTTT-5 from Texas Instruments is a high-performance fixed 5V, 3A linear voltage regulator designed for robust power management in demanding applications. Packaged in a DDPAK/TO-263-3 surface-mount form factor, it delivers stable output with a low dropout voltage of 0.6V (max) at 3A, ensuring efficient operation even with input voltages as low as 5.6V. The device supports an input voltage range up to 9V, making it suitable for systems powered by batteries or unregulated DC supplies. Its 650 µA quiescent current enhances energy efficiency, while advanced protection features like over-temperature, reverse polarity, short-circuit, and under-voltage lockout (UVLO) ensure reliability in harsh conditions.

UCC383TDKTTT-5 Features

• Fixed 5V Output: Precision-regulated voltage for stable power delivery.
• High Current Capacity: Supports 3A continuous output with minimal dropout.
