The LP38690DTX-2.5/NOPB from National Semiconductor (TI) is a fixed 2.5V low dropout regulator capable of delivering 1A. Its ultra-low 55µA quiescent current makes it highly efficient for battery-powered applications. Housed in a TO-252-3 package, this LDO provides robust thermal performance and stable output for high-current digital and analog loads.
- High Current Capacity: 1A output supports demanding digital loads.
- Ultra-Low Quiescent Current: 55µA minimizes power loss, ideal for battery operation.
- Thermally Efficient: TO-252-3 package dissipates heat effectively for reliable operation.
- Stable Output: 55dB PSRR at 120Hz reduces ripple for sensitive circuits.
