品牌:AISEMI型号:AS1084批号:10+封装:TO-263营销方式:现货产品性质:热销处理信号:数字信号制作工艺:半导体集成导电类型:双极型工作温度:-40~85(℃) 类型:稳压IC进口原装:AS1084,General DescriptionThe AS1084 is a series of low dropout positive voltageregulators with a maximum dropout of 1.5V at 5A ofload current.The AS1084 is available in 1.5V, 1.8V, 2.5V, 2.85V,3.3V and 5.0Vversions. The fixed versions integratethe adjust resistors. It is also available in an adjustableversion which can set the output voltage with twoexternal resistors.The series features on-chip thermal limiting whichprovides protection against any combination of overloadand ambient temperatures that would createexcessive junction temperatures. It also includes atrimmed bandgap reference and a current limiting circuit.The AS1084 series is available in standard packages ofTO-263 ( 2 and 3 lead ), TO-220 and TO-252.

The dropout voltage of the device is guaranteed maximum 1.3V at maximum outputcurrent, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress under overloadconditions on both the regulator and power source circuitry.The AMS1117 devices are pin compatible with other three-terminal SCSI regulators ...
