S Suraj143 Active Member Aug 11, 2010 #3 Hi Carl that's what I needed thanks for that. The problem is is there any way to get 5V/1.5A from that design Carl ? What changes do I have to do? 2-transistor Black Regulator I tried to contact Mr RB there is no way to contact him. Last edited: Aug 11, 2010
