The LP3965ESX-2.5/NOPB is a 1.5A low dropout linear regulator from Texas Instruments, providing a fixed 2.5V output. Its low dropout voltage of 0.55V at full load makes it highly efficient for 3.3V to 2.5V conversion. The TO-263 (DDPAK-5) package ensures good thermal performance. With a quiescent current of 9 mA, it offers a balance between efficiency and transient response, making it suitable for a wide range of digital and mixed-signal applications.
- Low Dropout: 0.55V at 1.5A minimizes power dissipation and allows operation from lower input rails.
- Compact Power Solution: 1.5A output in a TO-263 package reduces board space compared to discrete solutions.
- Stable Output: 9 mA quiescent current ensures fast load transient response without oscillation.
- Versatile Applications: Suitable for digital cores, post-regulation, and battery-powered devices.
FPGA and CPLD Core Power
The 1.5A output at 2.5V is well-suited for low-power FPGAs and CPLDs that require a stable core voltage.
DSP and Application Processors
Provides clean 2.5V rail for DSPs and application processors in portable and embedded devices.
Post-Regulation for 3.3V Systems
With only 0.55V dropout, it can efficiently regulate from a 3.3V rail down to 2.5V with minimal power loss.
Battery-Powered Handhelds
The low dropout extends battery life by allowing operation until the battery voltage drops close to 3.05V.
Networking Equipment
Stable 2.5V for PHY transceivers and switch ICs, with fast transient response for data bursts.
Test and Measurement Instruments
Precise 2.5V reference for analog-to-digital converters and sensor signal conditioning circuits.
