线性稳压器,LDO,150 mA,带延迟,可调重置和传感输出

Obsolete

概览

NCV4279A 是一款 5.0 V 精密微功率稳压器,具有 150mA 输出电流能力。输出电压精度范围为 ±2.0%,100 mA 下的最大漏电压为 0.5 V。其中一个特性是低静态电流,1.0 mA 负载时仅为 150 µA。该零部件适用于所有电池供电微处理器设备。微处理器控制逻辑包括一个带延迟的有效重置输出 RO 及一个 SI/SO 监控器,该监控器可用于向微处理器提供潜在的即将出现的重置信号的预警信号。由于采用了 SI/SO 监控器,在重置关闭微处理器之前,微处理器就可完成任何信号处理。有效重置电路可在低至 1.0 V 的输出电压下正常运行。在电源启动过程中或在正常运行期间,如输出压降超出规定限值,则激活重置功能。可将外部电阻分压器连接至 RADJ 引线,从而降低重置阈值电压。稳压器可防止电池反向、短路和热过载的情况发生。此器件可承受负载突降瞬变,适用于汽车环境。此器件还针对 EMC 条件进行了优化。如果应用需要在重置和检测逻辑输出布置上拉电阻,可以使用带集成电阻的 NCV4269A。
