The LM1117MPX-5.0/NOPB is a low dropout linear regulator from Texas Instruments, providing a fixed 5.0V output. It delivers up to 800mA of continuous current with a dropout voltage of just 1.2V, making it ideal for battery-powered and high-efficiency applications. The device features a low quiescent current of 5mA and excellent PSRR of 75dB at 120Hz, ensuring clean and stable output. Housed in a compact SOT-223-4 package, it is suitable for space-constrained designs.
- High Efficiency: Low 1.2V dropout voltage maximizes battery life by allowing operation closer to the input supply rail.
- Simplified Design: Fixed 5.0V output eliminates the need for external resistors, reducing BOM cost and board space.
- Clean Power Delivery: 75dB PSRR at 120Hz effectively filters ripple, ensuring stable operation for sensitive analog circuits.
- Robust Thermal Performance: SOT-223-4 package with exposed pad dissipates heat efficiently, enabling full 800mA output.
