Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1%. Current limit is trimmed to ensure specified Applications output current and controlled short-circuit current. Onchip thermal shutdown provides protection against any z PC Motherboard combination of overload and ambient temperature that z LCD Monitor would create excessive junction temperature. z Graphic Card The CP1117 eries is available in the industry z DVD-Vi deo Player standard SOT-223 power package z NIC/ Switch z Telecom Equipment z ADSL Modem z Printer and other Peripheral Equipment SOT-223 SOT-223 Pin Configurations INPUT OUTPUT ADJ/GND VOUT z Operation junction temp.: 0 to 125℃℃ TO-252 TO-252 INPUT OUTPUT ADJ/GND VOUT
