高速度, 低压差, ±1% 高输出精度，配ON/OFF功能CMOS双路稳压器

VRD 系列

概述

VRD系列乃高速度，低压差，高输出电压精度双路稳压器，以低压差来达成

高输出精度的规格。因双路稳压器的管道都是在IC内个别分开的，串音就能大

大减少。VRD系列的电压输出能在指定的温度范围内保证±1%的精度，而集

成电路内以温度系数调整的高准确率参考电压值来做基准。VRD系列以低ES

R电容来作输出的稳定作用。而已冲好的ESR电容能由VRD系列在CE=VSS的

情况下由内置的开关来放电，能助VOUT迅速回复到VSS水平。另外，VRD系

列也备有电流过高的保护电路，能防止电流通量超越输出三极管的限制电流容

量。

无卤素

RoHS

符合标准
