The LP3855ET-5.0/NOPB from Texas Instruments is a fixed 5V LDO regulator offering 1.5A output current. With a low dropout of 0.38V at full load and 3 mA quiescent current, it delivers efficient, stable power. The TO-220-5 package ensures excellent heat dissipation, and PSRR of 73dB to 57dB at 120Hz provides clean output for sensitive applications.
- High Current 5V Supply: 1.5A output for power-hungry loads.
- Low Dropout: 0.38V at 1.5A minimizes power loss.
- Superior Thermal Performance: TO-220-5 package for continuous operation.
- Good Noise Rejection: 73dB to 57dB PSRR at 120Hz.
