三端稳压IC：7805
三端正向电压调节器: 3-TERMINAL 1A POSITIVE VOLTAGE REGULATORS
The H78XXXX series can provide local on-card regulation,
eliminating the distribution problems associated with single point regulation.
Each employs internal current limiting,
thermal shut-down and safe operating area protection,
making it essen-tially indestructible.
If adequate heat sinking provided,
they can deliver over 1A outp current.
these devices can be used with external components to obtain adjustable voltages and currents.
FEATURES
◇ Output current up to 1A
◇ Output Voltages of 5V,6V,8V,9V,12V,15V,18V,24V
◇ No external components required
◇ Internal short circuit current limiting
◇ Internal thermal overload protection
◇ Output transistor safe-area compensation
◇ Output voltage offered in 3% & 5% tolerance
三端固定输出电压式稳压电源H78XXXX系列
运用其器件内部电路来实现过压保护、过流保护、过热保护
这使它的性能很稳定。能够实现1A以上的输出电流
器件具有良好
