LM10845A Low Dropout PosiTIve RegulatorsGeneral DescripTIonThe LM1084 is a series of low dropout voltage posiTIveregulators with a maximum dropout of 1.5V at 5A of loadcurrent. It has the same pin-out as NaTIonal Semiconductor’sindustry standard LM317.The LM1084 is available in an adjustable version, which canset the output voltage with only two external resistors. It isalso available in three fixed voltages: 3.3V, 5.0V and 12.0V.The fixed versions intergrate the adjust resistors.The LM1084 circuit includes a zener trimmed bandgap reference,current limiting and thermal shutdown.The LM1084 series is available in TO-220 and TO-263 packages.Refer to the LM1085 for the 3A version, and theLM1086 for the 1.5A version.Featuresn Available in 3.3V, 5.0V, 12V and Adjustable Versionsn Current Limiting and Thermal Protectionn Output Current 5An Industrial Temperature Range −40°C to 125°Cn Line Regulation 0.015% (typical)n Load Regulation 0.1% (typical)Applicationsn Post Regulator for Switching DC/DC Convetern High Efficiency Linear Regulatorsn Battery Charger
