| CP1117 Low Dropout Linear Regulator General Description The CP1117 is a series of low dropout three-terminal regulators with a dropout of 1.2V at 1A output current. The CP1117 has an adjustable version, that can provide the output voltage from 1.25V to 12V with only 2 external resistors. The CP1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1%. Current limit is trimmed to ensure specified output current and controlled short-circuit current. Onchip thermal shutdown provides protection against any combination of overload and ambient temperature that would create excessive junction temperature. The CP1117 eries is available in the industry standard SOT-223 power package PC Motherboard LCD Monitor Graphic Card DVD-Video Player NIC/Switch Telecom Equipment ADSL Modem Printer and other Peripheral Equipment Features Low dropout voltage: 1.2V at 1A output current Trimmed current limit On-chip thermal shutdown Three-terminal adjustable of fixed 1.5V, 1.8V, 2.5V, 3.3V, 5V Operation junction temp.: 0 to 125 J J Applications SOT-223 TO-252 Pin Configurations TO-252 3 3 VOUT 2 1 INPUT OUTPUT ADJ/GND VOUT 2 1 OUTPUT ADJ/GND INPUT SOT-223 * All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: server@ceramate.com.tw Tel:886-3-3214525 Http: www.ceramate.com.tw Page 1 of 12 Rev 1.4 Apr.29, 2005 Fax:886-3-3521052 CP1117 Low Dropout Linear Regulator Functional Block Diagram INPUT Thermal Shutdown Out + - OUTPUT GND (Fixed Output) ADJ (Adjustable Output) Figure 1.
