低噪声、稳压型、负输出电荷泵，用于GaAsFET偏置电源

MAX850-MAX853低噪声、反相电荷泵电源非常适合用于偏置蜂窝电话发射器放大器中的GaAsFET。\n\n MAX850-MAX852提供预设(-4.1V)和可调（-0.5V至-9.0V）输出电压。MAX853使用外部正控制电压来设置负输出电压。所有四款器件的输入电压范围均为4.5V至10V。输出电流为5mA。\n\n 内部线性稳压器将输出电压纹波降至2mVP-P。对于充分滤波的控制电压(VCTRL)，MAX853可实现低于1mVP-P的典型输出纹波。在整个温度范围内，最大电源电流为3mA，最大关断电流小于1µA（MAX851最大为5µA）。\n\n  \n • 5mA时提供-4.1V固定输出或-0.5V至-9V可调输出\n• 输入电压范围：4.5V至10V\n• 2mVP-P输出电压纹波(MAX850-MAX852)\n• 1mVP-P输出电压纹波(MAX853)\n• 100kHz电荷泵开关频率(MAX850/MAX851/MAX853)\n• 外部同步时钟输入(MAX852)\n• 逻辑电平关断模式：整个温度范围内最大1µA (MAX850/MAX852/MAX853)\n• 低成本、8引脚SO封装;
