Their benefits are such that it’s become surprisingly rare to see a traditional linear power supply with a mains-frequency transformer and rectifier circuit, so [ElectroBoy]’s dual voltage PSU ...

So what’s so exciting about this single-voltage linear power supply? Honestly, nothing — until you start looking at its thermally compensated current limiting circuit. This one is by ...

One popular type of variable DC power supply is the linear power supply (Figure 1), which is durable, accurate and delivers power with low noise. A linear power supply’s simple, direct feedback ...

As a visual aid, we’ll be cracking one open to expose its innards. Power supplies come in two main flavors: linear and switched mode. Linear power supplies are simpler, requiring only a few ...

In this article, we focus on two key application-oriented parameters of the linear regulator: Power Supply Ripple Rejection (PSRR) and output noise. These parameters have been discussed before (see ...

Meridian just released the Prime Power Supply, a special low-noise, highly regulated linear power supply designed to be the perfect partner to their Prime Headphone Amplifier. Its reference-quality, ...

Then, we’ll consider the features that you need to consider when selecting a power supply for an automated test system. Linear or switching supply? DC power supplies come in two basic flavours: linear ...

Polytron Devices is well-known for low-noise linear power supplies and can satisfy a wide range of custom needs such as: providing multiple output voltages in a single model; adding programmability or ...

In general for switching power supplies, efficiency range is from 70% to 92%, and for general linear regulators efficiency range is from 30% to 60%. LDO-based linear regulators, usually used for ...
