The Texas Instruments LP3966ES-2.5/NOPB is a high-current, fixed-output linear regulator delivering a precise 2.5V at up to 3A. Housed in a TO-263 (DDPAK-5) package, it features a low dropout voltage of 1.2V at full load, ensuring efficient operation even with tight input-output margins. With a quiescent current of 9 mA, this LDO provides clean, stable power for demanding digital and analog applications.
- High Current Capacity: Delivers up to 3A, suitable for powering high-performance processors and FPGAs.
- Low Dropout Voltage: 1.2V dropout at 3A maximizes efficiency and allows operation with lower input voltages.
- Fixed 2.5V Output: Provides a precise, stable rail without the need for external resistors.
- Robust TO-263 Package: Excellent thermal performance for high-power dissipation in industrial environments.
High-Current Digital Core Supplies
With a 3A output capability and a fixed 2.5V output, the LP3966ES-2.5/NOPB is ideal for powering the core voltage of FPGAs, DSPs, and ASICs that require stable, low-noise power.
Post-Regulation for Switching Converters
The low dropout of 1.2V at full load allows this LDO to efficiently clean up the output of a buck converter, reducing ripple and providing a precise 2.5V rail for sensitive analog circuits.
Industrial Control Systems
Its robust TO-263 package and 3A current rating make it suitable for industrial actuators, motor controllers, and PLC I/O boards that need a reliable 2.5V logic supply.
