The Texas Instruments UCC383TDTR-3 is a precision positive linear series pass voltage regulator designed for low-dropout applications. It provides a fixed 3.3V output voltage with a tight tolerance of ±1.5% at room temperature. This regulator is capable of delivering up to 3A of current while maintaining a low quiescent current of under 650 µA, irrespective of the load.
The UCC383TDTR-3 features a low dropout voltage, with a typical value of 0.45V at 3A and 50mV at 10mA, ensuring efficient operation even with minimal input voltage headroom. It includes protection features such as thermal shutdown, short-circuit power limiting, and reverse voltage sensing to prevent current flow in the reverse direction.
This device is supplied in a surface-mount DDPAK/TO-263-3 package, making it suitable for various electronic designs. The internal compensation eliminates the need for a minimum output capacitor. The regulator also offers logic shutdown capability and is internally compensated, simplifying circuit design.
Key electrical characteristics include a 3.3V fixed output, a maximum output current of 3A, and a typical dropout voltage of 0.45V at 3A. The operating temperature range is from 0°C to 70°C.
