BD450S5WFP2-C
车载用 500mA 5.0V, 具有关断功能, 输出电压恒定, LDO稳压器

BD450S5WFP2-C是45V耐压、输出电压精度±2%、输出电流500mA、静态电流38µA(Typ) 、输出电压恒定(3.3V或5.0V)的低静态电流稳压器。本IC非常适合用来降低电池直连系统中的消耗电流。可以启用或禁用“关闭输出”功能,针对支持该功能的产品,当对CTL引脚施加HIGH电压时,设备的输出ON;当施加LOW电压时,设备的输出OFF。输出相位补偿电容器可使用陶瓷电容器。另外,本IC还内置过电流保护电路,可防止输出短路等导致的IC损坏;内置过热保护电路,可防止IC因过负载状态等导致的热损坏。

本IC是为提高生产效率而对本系列产品中的BD450M5WFP2-C变更生产线后形成的型号,在新项目选型时,建议选择该型号,在技术规格书中的保证特性并没有差异。此外,由于文档和设计模型等也没有差异,因此除非另有说明,ROHM将公开BD450M5WFP2-C的数据。
