The LM1084IS-3.3/NOPB from Texas Instruments is a high-current fixed 3.3V linear regulator capable of 5A output. With a typical dropout of 1.5V at full load and 10mA quiescent current, it balances power and efficiency. The TO-263 package provides excellent thermal performance. Its 72dB PSRR ensures clean power for demanding digital and analog loads.
- High Output Current: 5A capacity supports processors, FPGAs, and high-power peripherals.
- Low Dropout: 1.5V typical at 5A minimizes headroom requirements.
- Excellent PSRR: 72dB at 120Hz filters supply noise effectively.
- Robust Thermal Package: TO-263 DDPAK-3 dissipates heat efficiently for sustained loads.
