JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD 1A LOW DROPOUT LINEAR REGULATOR CJA1117B-XXX SOT-89-3L FEATURES  Low Dropout Voltage: 1.15V at 1A Output Current  Trimmed Current Limit 1. ADJ/GND  On-Chip Thermal Shutdown 2. OUTPUT  Three-Terminal Adjustable or Fixed 1.8V, 2.5V, 3.3V, 5V 3.IN 2  Operation Junction Temperature: -40 ℃ to 125℃ GENERAL DESCRIPTION The CJA1117B-XXX is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current. The CJA1117B-XXX series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandage. reference to assure output voltage accuracy to be within 1.5%. 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 that would create excessive junction temperature. The CJA1117B-XXX has an adjustable version, that can provide the output voltage from 1.25V to 5V with only 2 external resistors. APPLICATIONS  PC Motherboard  LCD Monitor  Graphic Card  DVD-Video Player  NIC/Switch  Telecom Modem  ADSL Modem  Printer and other peripheral Equipment Marking: A1117B XXX Lot No. www.jscj-elec.com A1117B = Device code XXX: output voltage 1 Rev. - 2.0 ORDERING INFORMATION Package Operating Junction Temperature Range Part NO.
