LT3048 系列 - 采用 2mm x 2mm DFN 封装的低噪声偏置发生器
LT®3048系列可采用一个 2.7V 至 4.8V 的输入电压产生一个低噪声、低纹波偏置电源。
LT3048 包括一个升压型稳压器和一个 LDO 线性稳压器。升压型稳压器负责给线性稳压器供电。
升压型稳压器的输出电压被调节至比 LDO 输出高 1.1V，从而优化了 LDO 纹波抑制和瞬态响应性能。固定频率操作和电流模式控制允许使用非常小的电感器并产生低的可预知输出纹波。
LT3048 的线性稳压器可产生一个可编程的输出，而LT3048-XX则可产生固定输出电压。高电源纹波抑制能力与一个低噪声内部基准相组合，可产生小于 500μVP-P的输出纹波和噪声。
LT3048-15 采用 8 引脚 2mm x 2mm DFN 封装。
