概述及特點
FH62
系列是一組具有正向輸出電壓功½的三端穩
壓器，在輸入輸出壓差較小時也½提供出高電流。
通過
CMOS
工藝及鐳射剪切技術½產品具有½功
耗及高精度的優點。FH62 由一個高精密的電壓基
準源、一個可確認錯誤的回路、一個可限制輸出電
流的驅動器組成。

FH62
The FH62 series is a group of positive voltage output,
three-pin regulators. That provide a high current even
when the input/output voltage differential is small.
Low power consumption and high accuracy is
achieved through CMOS and laser trimming
technologies .The FH62 consist of a high-precision
voltage reference ,an error correction circuit, and a
current limited output driver ,Transient response to
load variations have improved in comparison to the
existing series .
SOT-23-3Land SOT-89 packages are available.
