Most modern power-supply control ICs offer built-in overcurrent or short-circuit protection. While some overcurrent-protection schemes are latching, others are nonlatching. When the overcurrent trip ...

Linear Technology Corporation announces the LT3065, a high voltage, low noise, low dropout voltage linear regulator offering precision, programmable current limit and a power good flag. The device ...

Power supply manufacturers sometimes hear from customers with unfortunate dilemmas, such as, “I need to operate the power supply outside its rated voltage range.” Or, “What happens if I exceed my ...

The improved one-BJT current-limiting supply is not much different than the primitive circuit, though its one additional resistor does change the circuit behavior. The improved circuit is shown below.

The unit also measures voltage, current, and power in real time, giving users a clear view of what their circuits are ...
