| Solved by SP1086 TM 1.5A Low Dropout Linear Regulator Features Low Dropout Voltage: Typical 1.3V at 1.5A Current Limiting and Thermal Protection Output Current: 1.5A Current Limit: 2.3A Operating Junction Temperature: 0 to 125oC Line Regulation: 0.015% (Typical) Load Regulation: 0.1% (Typical) Available in RoHS Compliant, Lead Free Packaging TO-220 3 2 1 INPUT OUTPUT ADJ/GND Applications High Efficiency Linear Regulators Battery Charger Post Regulation for Switching Supply Microprocessor Supply Motherboard Power Supply Cable and ADSL Modem DVD-Video Player Telecom Equipment Set Top Boxes and Web Boxes Modules' Supply general Description The SP1086 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 1.5A of load current. The series features on-chip thermal shutdown. It also includes a bandgap reference and a current limiting circuit. The SP1086 is available in 1.5V, 1.8V, 2.5V, 3V, 3.3V, and 5.0V versions. The fixed versions integrate the adjust resistors. It is also available in an adjustable version, which can set the output voltage with only two external resistors. The SP1086 series is available in standard packages of TO-263-3, TO-220, and TO-252. TO-263-3 TO-220 TO-252 Figure .
