78XX Regulator with Pass Transistor
{"Image DocumentName": "78XX Regulator with Pass Transistor", "Image ImageDescription": "Q1 starts to conduct when VR2 = 0.7 V. R2 is typically chosen so that max. IR2 is 0.1 A. Power dissipation of Q1 is P = (Vi - Vo)IL. Q2 is for current limiting protection. It conducts when VR1 = 0.7 V. Q2 must be able to pass max. 1 A; but note that max. VCE2 is only 1.4 V.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
