DC Power Supply (AC-DC power supply)

Circuit Method and Features of DC Power Supply

4. Noise Performance of Low-noise DC Power Supply LP5394

Further noise reduction of general linear regulator type power supplies and switching power supplies are not easy. On the other hand NF's LP5394 has almost no humming noise nor disturbance noise as well as supplying extremely low noise DC voltage (Figure 5 and 6) by not only circuit design, but also by firm structural design such as shielding make this achievement.
