LP3966ES-2.5 Description

Short technical summary and product information.

The LP3966ES-2.5 from Texas Instruments is a high-accuracy, low-dropout (LDO) linear voltage regulator designed for demanding applications. It can supply up to 3A of output current with a typical dropout voltage of 800mV.

 

This regulator operates with an input voltage range of 2.5V to 7V and offers a fixed output voltage of 2.5V. Key features include an Enable pin for control and a Power Good output signal that indicates the status of the output voltage. The device is designed for stability with a minimum load capacitance requirement of 33µF.

 

Available in DDPAK/TO-263-5 and TO-220 packages, the LP3966ES-2.5 is suitable for surface mount applications. It operates within a wide temperature range of -40°C to 125°C and includes overcurrent, overtemperature, and short-circuit protection features, making it a robust choice for power management solutions.
