ST稳压器L7812CV 7812 TO220 12V 1.5A

描述：L78xx系列三端阳性可在TO- 220调节器， TO- 220FP ，的TO- 3和D2PAK包和几个固定的的输出电压，使得它在很宽的范围内有用的应用程序。这些稳压器可提供本地上牌监管，消除了与单点相关分配问题调节。每种类型采用内部电流限流，热停机和安全区保护，使得它本质上坚不可摧。如果提供足够的散热，他们可以提供超过1 A的输出电流。虽然设计主要作为固定电压稳压器，这些设备可以与外部元件中使用获得可调节的电压和电流。

Description

The L78 series of three-terminal positive regulators is available in TO-220,

TO-220FP, D2PAK and DPAK packages and several fixed output voltages, making it

useful in a wide range of applications.

These regulators can provide local on-card regulation, eliminating the distribution

problems associated with single point regulation. Each type embeds internal current

limiting, thermal shut-down and safe area protection, making it essentially

indestructible. If adequate heat sinking is provided, they can deliver over 1 A output

current. Although designed primarily as fixed voltage regulators, these devices can

be used with external components to obtain adjustable voltage and currents
