The LP3965EMP-3.3 is a fixed 3.3V low dropout linear regulator capable of delivering 1.5A of output current. With a dropout voltage of just 0.55V at full load, it maintains regulation even with tight input-output headroom. The SOT-223-5 package offers a compact footprint for space-constrained designs, while the 9mA quiescent current supports efficient operation in battery-powered systems.
- High current capacity: 1.5A output supports demanding loads without external pass transistors.
- Low dropout: 0.55V at 1.5A maximizes efficiency in low-headroom applications.
- Compact SOT-223-5 package: Saves PCB space while providing adequate thermal dissipation.
- Fixed 3.3V output: Simplifies design with no external resistor divider needed.
