For comparison a 12V Zener diode biased at 1 mA is also plotted. The LM317 sometimes gets a reputation in print as being an unacceptable regulator to use in low noise circuits, but with proper ...

However, some ultra-low-noise applications such as instrumentation and high-quality audio require even lower noise. For that purpose, the Figure 1 circuit includes an external transistor and ...

In addition, an ultra-low output noise voltage of just 3.0 μVrms, makes it suitable for high-quality audio DACs and other audio equipment to ensure stable and noise-free audio output even under ...

Many low-dropout-voltage regulators see service in electronic systems, but relatively few are designed for low-noise operation. (For example, Maxim's MAX8887 achieves a noise voltage of approximately ...

You can use a simple boost converter, a filter circuit to reduce electromagnetic interference (EMI), and a little trickery to build a compact, ultra-low-noise, phantom power supply (48 V) that ...

Low-noise LDOs for Hi-Fi circuits up to 1A Rohm has introduced ‘high-fidelity’ power supply ICs aimed at audio devices requiring high-resolution audio play-back. Above the quality of CD audio, it sees ...
