RT9053A 是高性能的 400mA 低压差线性稳压器,其静态电流消耗仅 42μA,可最大程度地延长电池使用时间。它可与低 ESR 陶瓷电容配合稳定工作,对板面空间要求不高,有利于掌上型无线设备的设计工作。RT9053A 在关机模式下的电流消耗仅 0.7μA,其直通压降低,输出电压精度高,还有电流限制保护功能。其封装为 SOT-23-5 和 WDFN-6L 2x2 。
可调输出电压,最低可达 0.8V
输入电压范围: 2.2V~5.5V
低压差: 230mV@400mA
对输入、输出的瞬态变化响应极快
电流限制保护
热关机保护
仅需 1μF 输出电容即可稳定工作
符合 RoHS 规范,不含卤素
