Circuit adds foldback-current protection

For many applications that require power-supply currents of a few amperes or less, three-terminal adjustable-output linear voltage regulators, such as National Semiconductor’s LM317, offer ease of use, low cost, and full on-chip overload protection. The addition of a few components can provide a three-terminal regulator with high-speed short-circuit current limiting for improved reliability. The current

Short circuit protection for (almost) any power supply

Step 1: Understanding the circuit The circuit is really easy to understand. A resistor of low value (the resistor value will be explained later) is connected in series with the output of the power supply. As current starts to flow through it, a small voltage drop will appear on it and we will use this

Hardware Protection – OverVoltage and OverCurrent

Power processing is one of the most important aspects on electronic design. The power is unique for a typical system because it gives the system life. Before starting to make the project for a power supply we need to analyze some aspects: Which kind of radio/electromagnetic interference is the device going to face ? What
