The LP3855ESX-2.5/NOPB is a low-dropout linear regulator from Texas Instruments, offering a fixed 2.5V output at up to 1.5A. With a dropout voltage of just 0.38V at full load, it is highly efficient for post-regulation applications. The device features a quiescent current of 3 mA and excellent PSRR of 73dB at 120Hz, ensuring clean, stable power. Its TO-263 (DDPAK-5) package provides good thermal performance for industrial and networking applications.
- Low Dropout Voltage: 0.38V at 1.5A enables efficient operation from a 2.8V or 3.3V input.
- High PSRR: 73dB at 120Hz effectively filters input ripple, ideal for noise-sensitive circuits.
- 1.5A Output Current: Suitable for powering multiple digital ICs or medium-power loads.
- Thermally Efficient Package: TO-263 (DDPAK-5) dissipates heat effectively in continuous operation.
