illustrate

LM2750是一个稳压开关电容倍增，产生低噪声输出电压。 5.0V输出电压选项（LM2750 - 5.0）可提供高达120mA的输出电流超过2.9V到5.6V输入范围，以及输出电流40毫安当输入电压低至2.7V。 也可用类似的输出电流能力的可调输出电压选项（LM2750 - ADJ）。 LM2750已被安置在美国国家的10引脚LLP封装，具有优良的热性能保持过热的部分几乎所有的额定工作条件

为空间受限，电池供电应用的一个完美契合，LM2750只需要3个外部元件：一个输入电容，一个输出电容，和一个飞电容。 建议使用小型，廉价的陶瓷电容器。 这些电容器，1.7MHz的固定开关频率的LM2750一起，产量低输出电压纹波，需要一个低噪声电源系统有益。 预调最大限度地减少输入电流纹波，输入噪声减少到可以忽略不计的水平。

严格控制的软启动功能，限制了部分激活浪涌电流。 完全关闭负载从输入断开。 输出电流限制和热关断电路保护输出短路或过大的电流负载时，LM2750和连接​​的设备。
