    Tips: Are there any limitations to using a variable linear DC power supply?

    Variable linear DC power supplies have certain limitations. They are typically larger, heavier, and less energy-efficient than their switching counterparts. Linear power supplies dissipate excess voltage as heat, leading to lower efficiency, especially when providing high output voltage or current. Additionally, they may have limited maximum output power. The output voltage regulation may not be as precise, and there can be a risk of voltage fluctuations under varying loads. Linear power supplies might also be more expensive due to the larger transformers and heat sinks required. In comparison to switch-mode power supplies, they may have slower response times and may not be as suitable for certain applications requiring rapid changes in voltage or current.
