LD1117A

1 A Low Dropout Positive Voltage Regulator LD1117A 1A Low Dropout Positive Voltage Regulator General Description LD1117A is a three terminal low dropout positive voltage regulator with a dropout of 1.15V at 1A output current. LD1117A is available in an adjustable version which can set the output voltage 1.25V to 12V with only 2 external resisitors.In addition,it is also available in 7 Fixed output voltages: 1.2V,1.5V,1.8V,2.5V,2.85V,3.3V an 5.0V SOT-223 SOT-89 LD1117A provides current limiting and thermal shutdown. Its circuit includes a trimmed Bandgap reference to assure output voltage accuracy to be within ±1.0% for fixed output voltage version and ±2.0% for adjustable output voltage version. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal shutdown provides protection against any combination of overload and ambient temperature TO-220 that would create excessive junction temperature LD1117A series are available in SOT-223 ,SOT-89 ,TO-220,DPAK (TO-252) and D2PAK (TO-263-3) Packages Features Input Voltage up to 20V Output Current up to 1A Low Drop Output Voltage:Typical 1.15V at 1A output current Trimmed Current Limit and On-Chip Thermal Shutdown Operation Junction Temperature: -40°C to 125°C RoHS Compliance and Halogen Free DPAK （TO-252） D2PAK （TO-263-3） Applications PC Mother Board Graphic Card NIC/Switch LCD Monitor , DVD Video Player and Printer Telecom Equipment and other P...
