This file type includes high-resolution graphics and schematics when applicable. A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output.
The adjustment is done by first turning potentiometer P1 to maximum (wiper to the side of the 78L05) and subsequently turning trimpot P2 until the desired maximum output voltage is reached. P1 is then ...
The potentiometer R2 is often the most unreliable part of the circuit. As shown in the expression above, a breakdown of the potentiometer (e.g., loss of contact, open circuit) maximizes the effective ...
A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output. Typically, the output voltage is determined by the ratio of two resistors. Replacing ...
