FS8855 500mA LDO Linear Regulator General Description The FS8855 is a low-dropout linear regulator that operations in the input voltage range from +2.5V to +9.0V and delivers 500mA output current. The high-accuracy output voltage is preset at an internally trimmed voltage 2.5V or 3.3V. Other output voltages can be mask-optioned from 1.3V to 4.5V with 100mV increment, except FS8855-29Cx which has 2.85V output voltage. The FS8855 consists of a 1.25V bandgap reference, an error amplifier, and a P-channel pass transistor. Other features include short-circuit protection and thermal shutdown protection. The FS8855 devices are available in TO-92, SOT-89 and SOT-223 packages.

物料型号： - FS8855-xxCD, FS8855-xxCE, FS8855-xxCF, FS8855-xxCW, FS8855-xxCG, FS8855-xxCH, FS8855-xxCJ, FS8855-xxCK, FS8855-xxCL, FS8855-xxCI, FS8855-xxCY

器件简介： - FS8855是一款低dropout线性稳压器，输入电压范围从+2.5V至+9.0V，可提供最大500mA的输出电流。内部高精度输出电压预设为2.5V或3.3V，其他输出电压可通过掩模选项从1.3V至4.5V以100mV增量设定，除了FS8855-29Cx输出电压为2.85V。FS8855由1.25V带隙参考源、误差放大器和P沟道通晶体管组成，还包含短路保护和热关断保护功能。FS8855有TO-92、SOT-89和SOT-223三种封装。

引脚分配： - IN：调节器输入引脚，供电电压范围2.5V至9.0V，需与地之间旁路接1µF电容。 - OUT：输出电压引脚，可提供至500mA电流，需与地之间旁路接3.3µF电容。 - GND：提供所有电压的参考，应与IN和OUT引脚共享铜面积以优化散热。

参数特性： - 输入电压(VIN)：2.5V至9.0V - 输出电压(VOUT)：在VIN=VOUT+0.8V，IOUT=1mA条件下，VOUT±30mV至VOUT±42mV - 最大负载电流(IMAX)：500mA - 电流限制(ILIMIT)：0.8A - 短路电流(IsC)：在VOUT=0V条件下，350mA至400mA - 地引脚电流(IQ)：65µA至120µA - dropout电压(VDROP)：在IOUT=1mA时为1mV至1.2mV，IOUT=500mA时为650mV至800mV - 线路调整率(AVLINE)：0.2%至0.3%/V - 负载调整率(AVLOAD)：0.01%/mA至0.02%/mA - 输出噪声(eN)：在1Hz至10KHz，COUT=3.3µF条件下，75µVRMS - 抑制比(PSRR)：在10KHz，COUT=3.3µF条件下，75dB - 热关断温度(TSD)：155°C - 热关断滞后(THYS)：20°C - 热阻(OJA)：SOT-223为155°C/W，SOT-89和TO-92为180°C/W

功能详解： - FS8855包含一个限流器，监控并控制通晶体管的栅极电压，将输出电流限制在0.8A以内。FS8855是一个低dropout线性稳压器，提供预设的2.5V和3.3V输出电压，特殊输出电压掩模选项从1.3V至4.5V。FS8855由1.25V参考源、误差放大器、P沟道通晶体管和内部反馈电压分压器组成。FS8855还包含热关断保护功能，当结温超过+155°C时，热传感器关闭通晶体管以降低IC温度。在结温降低20°C后，热传感器再次打开通晶体管，因此在持续热超载条件下输出会呈现脉冲状。

应用信息： - CD-ROM驱动器、DVD-ROM驱动器、便携式消费设备、无线电控制系统、无线通信系统。
