RT9012是双输出、低噪声、低压差的 300mA 线性稳压器,其输出电压范围为 1.2V~3.5V ,输入电压范围为 2.5V~5.5V。RT9012 的输出电压精度为 2%,具有极低的输入输出电压降 (240mV@300mA) 和很低的静态电流 (每路27μA),其关机电流几乎趋于0,是电池供电的便携式设备的理想之选。它的保护功能包括电流限制、输出短路保护和过温保护。RT9012 采用了短路热折回保护方式。当因为输出端短路 (VOUT < 0.4V) 而发生热保护时,其过温保护触发温度从165°C下调至110°C,为最终用户提供最大限度的安全支持。RT9012 可与很低容量的陶瓷输出电容的配合稳定工作,对 PCB 空间要求极低,使用成本低廉。RT9012 的输出电压是固定的,其封装为 WDFN-8L 2x2 规格。
