我的7806输入电压只得7V,输出只有5.3V,不够供6N11的。现在想弃掉7806,由以下电路取代<img src="attachments/dvbbs/2004-12/2004125115044753.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-12/2004125115044753.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />[em11][em11][em11][em11][em11][em11]。 |
