Adjustable Low-Dropout Voltage Regulator
This circuit is based on a design for a low-dropout voltage regulator in the book 303 Circuits (published by Elektor in 1998). The author adapted the design to make the output voltage adjustable, and he designed a new PCB for SMDs. However, the power transistor is still an ‘old-fashioned’ type.
