EC50117C 1A Low Dropout Positive Voltage Regulator GENERAL DESCRIPTION FEATURES The EC50117C Series are available in fixed and adjustable output voltage versions. Over current and thermal overload protection are integrated onto the chip. Output current will decrease while it reaches the preset current or temperature limit. The dropout voltage is specified at 1.2V Maximum at full rated output current. EC50117C Series provide excellent regulation over variations due to changes in line, load and temperature. EC50117C Series are three terminal regulators and available in popular packages. ● Low Dropout Voltage 1.2V at 1A ● Adjustable or Fixed Voltage (1.8V, 2.5V, 3.3V, 5V) ● Over Current Protection ● Thermal Overload Protection ● Maximum Line Regulation 0.45% ● Maximum Load Regulation 0.4% ● Adjust Pin Current Less Than 90 uA Applications ● SCSI-2 Active Termination ● High Efficiency Linear Regulators ● 5V to 3.3V Voltage Converter ● Battery Charger ● Battery Management Circuits For Notebook And Palmtop PCs ● Core Voltage Supply: FPGA, PLD, DSP, CPU PIN ASSIGNMENT Package: SOT89-3L Package: SOT89-3L (Pin type A) Package: TO252-3L Package: SOT223-3L E-CMOS Corp.
