描述:
MSK 5131系列稳压器可在+1.5V， +1.7V， +1.8V，+1.9V，+ 2.5V， +3.3V。+5.0V ac +12.0V配置。由于使用了具有单片技术的超级PNP输出通晶体管，所有产品都拥有超低dropout规格。在这种配置中，3安培的跌落电压为350mV，这提高了效率，降低了功耗。精度是保证1%的最大输出电压公差。该系列还提供了兼容TTLICMOS的开/关使能功能。MSK 5131系列封装在一个空间高效的5nin电源SIP可在两种风格与三个铅弯接头.
特点:电隔离的顶部Tab或Z Tab SIP极低跌落电压:350mv @3安培在+ 1.5 v, v + 1.7, + 1.8 v, v + 1.9, + 2.5 v, v + 3.3, + 5.0 v和+ 12.0 vTTL电平使能引脚:零电流关闭模式反向电池和负载转储保护低接地电流:42mA典型满载时最大保证精度输出电流到3安培.
旁路电容对于大多数应用来说，一个最小33uF，低ESR(0.5-2欧姆)的钽电容应该尽可能靠近稳压器的输出。这将有效地降低稳压器的输出阻抗，增加瞬态响应，并消除通常与低压差稳压器相关的任何振荡。额外的旁路电容器可以用于远程负载位置，以进一步改善调节。这些可以是钽或电解的变种。除非稳压器非常靠近电源滤波器电容，否则稳压器的输入端还应该添加一个4.7uF的最低ESR(0.5-2欧姆)钽电容。如果需要，电解液也可以被取代。当用电解电容器代替钽电容器时。
一个很好的经验法则是将电解液的尺寸增加到钽值的10倍以上负载调整率为了最好的结果，接地引脚应该直接连接到负载如下所示，这有效地减少了接地环效应，并消除在意义上的过电压降。同样重要的是保持稳压器和负载之间的输出连接尽可能短，因为这直接影响负载调节。例如，如果使用20规线，其电阻约为每英尺0.008欧姆，这将导致在1安培负载电流下降8mV/ft。为了获得最佳的性能，遵循电容器选择准则也很重要。连接图见图2。
