高速度, 低压差, ±1% 高输出精度,配ON/OFF功能CMOS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
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
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

Outline
VRD series are high-speed, low dropout voltage, high output voltage accuracy dual regulator, low dropout to achieve High output accuracy specifications. Because dual regulator IC in the pipeline are individual separate, crosstalk can be large Greatly reduced.

Applications
 Battery powered products
  _ Phone
  _ Digital camera or camcorder
 Portable games
 Handheld instruments
