The LM2940IMP-10/NOPB from Texas Instruments is a 1A low dropout linear regulator delivering a fixed 10V output. With a low 1V dropout at full load and 63dB PSRR at 120Hz, it provides clean, stable power for audio, industrial, and test equipment. The SOT-223-4 package offers a compact surface-mount solution with good thermal performance.
- High Current Capacity: 1A output supports demanding loads and multiple circuits.
- Excellent Ripple Rejection: 63dB PSRR at 120Hz eliminates mains hum in audio applications.
- Low Dropout: 1V dropout at 1A maximizes efficiency from 11V input rails.
- Compact SMD Package: SOT-223-4 saves board space while dissipating heat effectively.
Audio Amplifier Power Rails
