The LP3855ET-3.3/NOPB is a fixed 3.3V LDO regulator from Texas Instruments, delivering up to 1.5A. Its low dropout of 0.38V at full load and 3 mA quiescent current make it efficient for high-current applications. The TO-220-5 package provides superior thermal dissipation, while PSRR of 73dB to 57dB at 120Hz ensures clean output.
- High Output Current: 1.5A capability for demanding loads.
- Low Dropout Voltage: 0.38V at 1.5A reduces power dissipation.
- Thermally Efficient: TO-220-5 package ideal for continuous high-current operation.
- Stable 3.3V Rail: Reliable for digital and mixed-signal circuits.
