The LP3962EMP-3.3/NOPB is a high-current 3.3V low-dropout regulator from National Semiconductor, capable of delivering 1.5A. With a typical dropout of just 0.55V at full load, it efficiently regulates from 5V supplies. The SOT-223 package provides a compact solution for space-limited designs requiring substantial output current.
- High Output Current: 1.5A capability supports demanding digital loads like FPGAs and DDR memory.
- Low Dropout Voltage: 0.55V at 1.5A minimizes power dissipation and allows operation from lower input voltages.
- Compact SOT-223 Package: Saves board space while providing adequate thermal performance for 1.5A operation.
- Fixed 3.3V Output: Simplifies design with no external feedback components required.
