I have built a power supply using an LM317: simulate this circuit – Schematic created using CircuitLab When the supply is on for a rather long time (several hours) with a respectable ...
I am trying to build a simple circuit that takes a 9v battery through a voltage regulator that outputs 1.5v across a load resistor . The load will be just a piece of metal that gets heated up. My ...
I'm using a 5V/2A voltage regulator (L78S05) without a heatsink. I'm testing the circuit with a microcontroller (PIC18FXXXX), a few LEDs and a 1mA piezzo buzzer. The input voltage is ~24V DC. After ...
I've designed a simple PWM RGB LED slow fader to be used as a garden lighting effect. My circuit works great, but I under-estimated the amount of heat that is generated by the 7805 linear regulator. ...
