LP3963ES-3.3 Description

Short technical summary and product information.

The Texas Instruments LP3963ES-3.3 is a fixed-output low dropout (LDO) linear voltage regulator designed to deliver a regulated 3.3V output at up to 3A. It features a typical dropout voltage of only 1.2V at full load, making it suitable for applications where the input voltage is close to the output voltage.

 

The regulator includes an enable control feature and built-in protection against over current, over temperature, and short circuit conditions. Output voltage accuracy is ±1.5% typical, and load regulation is 0.06% typical. The quiescent current in shutdown mode is 15µA, helping to preserve battery life in portable designs.

 

The LP3963ES-3.3 is offered in a DDPAK/TO263-5 surface-mount package and operates over a junction temperature range of -40°C to +125°C. The input supply range is +2.5V to +7.0V.
