线性稳压器,LDO,400 mA,带启用,延迟,可调重置和通用比较器

Obsolete

概览

NCV8503 是一个精确微功耗稳压器系列,具有 400mA 输出电流能力。该系列的输出电压选项为可调、2.5 V、3.3 V 和 5.0 V,准确度在 ±2.0% 范围内。全负载下的最大漏电压为 0.6 V。低静止电流在器件关断时的拉电流仅为 1µA。此零件适用于所有电池供电的微处理器设备。微处理器控制逻辑还包括了有效重置(带延迟)。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联接至 RADJ 引线,从而降低重置阈值电压。参考通用比较器(标志/监控器)与一个温度温度电压进行比较,并在开极集极输出处提供 1.0 mA 的驱动电流。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,因此在重置关断微处理器之前,微处理器有时间完成任何信号处理。该稳压器针对电池逆向、短路和热过载情况进行保护。此器件可承受负载转储瞬变,适用于汽车环境。
