What is low noise power supply?
Low Noise Linear Regulators. For portable systems that require low output voltage noise, a linear regulator is often the “go to” choice for system power. Ideally, the linear regulator is powered directly from the battery source rather than an intermediate DC/DC converter for lowest noise performance.
What is ripple and noise?
Ripple and Noise Ripple is the inherent ac component of the output voltage caused by the internal switching of the power supply. Noise is the manifestation of parasitics within the power supply that appear as high frequency voltage spikes on the output voltage.

What’s the problem with a cheap power supply?
The problem with [Richard]’s broken power supply were voltage and current adjustments knobs. This cheap power supply didn’t use rotary encoders – voltage and current were controlled by a pair of 1k and 10k pots. Replacing these parts cost about $5, and [Richard]’s power supply was back up on its feet.
