Current limiter schematic

WebFeb 22, 2015 · Designing the circuit for 3A range makes it difficult to set e.g. 20 mA exactly. Not a property of the circuit in particular but of the involved component parameters, e.g. OP offset voltage. Another general remark. Operating a linear current limiter at higher currents involves large power dissipation for the output transistor (P = I*V). http://www.discovercircuits.com/L/limiter.htm
