概述
ADP7102是一款CMOS、½压差线性调节器,采用3.3
V至
20 V电源供电,最大输出电流为300 mA。这款高输入电压
LDO适用于调节19 V至1.22 V供电的高性½模拟和混合信
号电路。该器件采用先进的专有架构,提供高电源抑制、
½噪声特性,仅需一个1
F小型陶瓷输出电容,便可实现
出色的线路与负½½瞬态响应性½。
ADP7102提供7个固定输出电压选项和可调输出型号,可通
过外½反馈分压器,将输出电压调节至1.22
V至VIN − VDO。
ADP7102输出噪声电压为15
V rms,并不受输出电压½
响。这些器件具有一个“电源良½”数字输出引脚,允许电
源系统监控器检查输出电压是否正常。用户可编程精密欠
压闭锁功½方便控制多个电源的时序。
ADP7102提供8引脚3
mm × 3 mm LFCSP和8引脚SOIC两种
封装。LFCSP不仅提供一种超紧凑的解决方案,而且散热
性½出色,在小尺寸薄型电路板空间中满足高达300
mA输
出电流的应用需求。
