The LP3962ESX-2.5/NOPB is a fixed 2.5V low dropout linear regulator capable of delivering 1.5A of output current. With a dropout voltage of just 0.55V at full load, it is ideal for applications requiring high efficiency from a low input-to-output voltage differential. The TO-263 (DDPAK-5) package ensures robust thermal performance. This regulator provides a clean, stable power supply for digital cores, analog circuits, and post-regulation stages.
- High Current Capacity: Delivers up to 1.5A, suitable for powering demanding digital loads like FPGAs and DSPs.
- Low Dropout Voltage: 0.55V at 1.5A allows operation with minimal input-to-output headroom, reducing power dissipation.
- Stable Fixed Output: Provides a precise 2.5V rail, eliminating the need for external resistor dividers and ensuring accuracy.
- Robust Thermal Package: The TO-263 (DDPAK-5) package efficiently dissipates heat, ensuring reliable operation at high currents.
FPGA and DSP Core Power
Modern FPGAs and DSPs require precise, low-noise 2.5V core supplies. The LP3962ESX-2.5/NOPB delivers up to 1.5A with a low 0.55V dropout, ensuring stable operation even during dynamic load transients.
Post-Regulation for Switching Converters
Use this LDO after a buck converter to attenuate switching noise and ripple. Its low dropout voltage allows efficient operation with a small headroom, maximizing system efficiency.
Battery-Powered Portable Devices
