LM338可调三端稳压器提供5A的平均输出电流，输出电压范围为1.2V至32V连续可调 。
LM338 内置过载保护电路，自动限制功耗。此保护电路允许瞬态负载强电流通过，12A 以内
的瞬态电流不会实施保护，以利于某些设备的顺利启动(LM338 adjustable three-terminal stabilizer provides the average output current of 5A, and the output voltage range is 1.2V to 32V continuously adjustable.
LM338 built-in overload protection circuit automatically limits power consumption. This protection circuit allows transient load strong current to pass within 12A
The transient current will not be protected to facilitate the smooth start of some equipment)
