Infineon Technologies IFX1763 宽输入范围低噪音 LDO 稳压器
英飞凌 IFX54441 宽输入范围低噪音 LDO 稳压器是微功率、低压差稳压器,采用紧凑的 SMD 封装。这些器件能够提供 300mA 的输出电流,压差仅为 270mV。30μA 的低静态电流使其成为电池供电系统的理想选择。低输出噪音是 IFX54441 的一项关键特性。增加一个 0.01μF 的外部旁路电容器后,在 10Hz 到 100kHz 的带宽上 输出噪音值降至 24μVRMS。小至 3.3μF 的输出电容器可令 IFX54441 稳压器保持稳定。可使用小型陶瓷电容器,无需用到很多其他稳压器所需的串联电阻。特性
