描述 Description

The AS78XXA series are three terminal positive
voltage regulators designed for a wide variety of applications
including local, on-card regulation.
The AS78XXA are complete with internal current limiting,
thermal shutdown protection, and safe-area compensation
which make them virtually immune from
output overload. If adequate heat sinking are provided,
these regulators can deliver output currents up to 1A.
The AS78XXA are available in TO-252-2 (1), TO-
252-2 (3), TO-252-2 (4), TO-220-3 and TO-220F-3
packages.

简介

AS7805A属于集成电路（IC）的线性+开关稳压器。由Diodes制造生产的AS7805A稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
