Is It Normal For Voltage Regulator To Get Hot at Wendell Barba blog

Is It Normal For Voltage Regulator To Get Hot. Your part has a thermal resistance of 50 degrees c/w, so the. At 95 ma, you are dissipating 0.095 x 19.15 or 1.8 watts. The most common reasons for a voltage regulator failure are damaged wires, loose connections, corroded battery terminals, excessive voltage input, overheating of an electrical component, and a regulator that has reached the end of its life. Is this a normal behaviour for this regulator? Most modern monolithic voltage regulators (lm340, lm317, lm78xx, etc plus the negative voltage versions) that do not have an. Typically the input voltage to the regulators should be at least 3 volts higher than the desired output voltage, not to exceed 24 volts (35 volts for the 24 volt device). 4v at 200ma means you're dissipating 800mw of power in the regulator as heat. The heat produced by a voltage regulator isn't a function of the voltage, it's a function of the power. The heat is caused by the voltage drop across the regulator and the current running through it. You can calculate the power the voltage. What could cause it to heat that much?
