L78L12ABUTR 原装全新 开关稳压器 线性 的描述
L78L系列三端正极调节器采用内部电流限制 还有热关闭,使它们基本上坚不可摧。如果有足够的散热器 是提供的,他们可提供高达100 mA的输出电流。他们的目的是 作为固定电压调节器在广泛的应用,包括本地或单卡调节,以消除噪音和分布相关的问题 单点调节。此外,它们还可以与电源传递元件一起使用 制造大电流调压器。L78L系列用作齐纳二极管/电阻器 组合更换,提供了e改进与较低的静止电流 和较低的噪音。
The L78L series of three-terminal positive regulators employ internal current limiting
and thermal shutdown, making them essentially indestructible. If adequate heat-sink
is provided, they can deliver up to 100 mA output current. They are intended
as fixed voltage regulators in a wide range of applications including local or oncard regulation for elimination of noise and distribution problems associated with
single-point regulation. In addition, they can be used with power pass elements to
make high-current voltage regulators. The L78L series used as Zener diode/resistor
combination replacement, offers e improvement along with lower quiescent current
and lower noise.
