TPL740F33/TPL740F18 500mA输出高PSRR低损耗线性稳压器

　　The TPL740 series products are high performance and low dropoutlinear regulators.The TPL740 series products support a maximum 500mA output current with low quiescent current and high PSRR.TheTPL740 series products are stable with ceramic output capacitorfrom 2.2μF to 10μF.The TPL740 series products have a high PSRR with60 dB at 1 kHz.This feature makes TPL740 series products verysuitable for power-sensitive applications with high noise from theprevious stage power supply.As low as 49μA quiescent current andonly 20 nA shutdown current makes the TPL740 series products idealchoices for portable devices with battery power supply.Currentlimit foldback and thermal overload protection circuits improve thereliability under heavy load conditions.The TPL740 series productsprovide several output voltage version options including fixedversion and adjustable version with±2%output voltage accuracy overoperating conditions.The TPL740 series products are guaranteed overthe junction temperature range from–40°C to+125°C. 　　Features　　Input Voltage Range:2.4 V to 5.5 V 　　Output Voltage Options:　　−Fixed Voltage:1.2 V,1.5 V,1.8 V,2.5 V,2.7 V, 　　2.8 V,2.9 V,3V,3.3 V 　　−Adjustable Voltage:0.8 V to 5 V 　　High Output Accuracy:　　−±1%Typical Under Room Temperature 　　−±2%Through OperatingConditions 　　Maximum Output Current:500 mA 　　Low DropoutVoltage:400 mV at 500 mA 　　Low Quiescent Current and ShutdownCurrent 　　Foldback Current Limit and Thermal Protection 　　Stablewith 2.2μF Ceramic Capacitor 　　Inrush Input Current LimitationDuring Start-up 　　Thermal Shutdown Protection 　　JunctionTemperature Range:−40°C to+125°C 　　Packageoptions:SOT23-5,SC70-5,SOT89-3, 　　1×1 DFN-4 　　Applications　　Handheld Devices with Battery Power Supply 　　POS 　　VideoSurveillance 　　Wireless and IoT modules
