UCC383TD-3 Description

Short technical summary and product information.

The Texas Instruments UCC383TD-3 is a high-performance, 3-Amp low dropout linear voltage regulator designed for various power management applications. This device features a fixed 3.3V output voltage and a low dropout voltage of typically 400mV when operating at its maximum output current of 3A. It also maintains a low dropout of 50mV at 10mA.

 

The UCC383TD-3 operates with an input voltage range from 2.8V to 9V, making it suitable for a wide array of systems. Its quiescent current is typically under 650µA, irrespective of the load, contributing to power efficiency. The regulator includes essential protection features such as overcurrent protection, reverse current protection, and thermal shutdown.

 

Packaged in a TO-263 surface-mount package, the UCC383TD-3 is designed for ease of integration into printed circuit boards. The operating temperature range is from 0°C to 70°C. This component is part of the UCC383 series of low-dropout linear regulators from Texas Instruments.

 

Key electrical characteristics include a PSRR of 18dB at 100KHz and an accuracy of 2.5%. The device also offers a logic shutdown capability. It is noted as RoHS3 compliant but not lead-free.
