The LM2940IMP-5.0/NOPB from Texas Instruments is a 1A low dropout linear regulator delivering a fixed 5V output. With a low 1V dropout at full load and 64dB PSRR at 120Hz, it provides clean, stable power for microcontrollers, automotive systems, and industrial controls. The SOT-223-4 package offers a compact surface-mount solution.
- High Current Capacity: 1A output supports power-hungry digital loads.
- Good Ripple Rejection: 64dB PSRR at 120Hz filters mains noise effectively.
- Low Dropout: 1V dropout at 1A maximizes efficiency from 6V input rails.
- Versatile Package: SOT-223-4 balances size and thermal performance.
Microcontroller Power Supply
Provides a stable 5V rail for MCUs, sensors, and digital logic in embedded systems with up to 1A current draw.
