L7885C集成电路（IC）的线性+开关稳压器规格书PDF中文资料

L7885C属于集成电路（IC）的线性+开关稳压器。由意法半导体集团制造生产的L7885C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。

Description

The L7800 series of three-terminal positive

regulators is available in TO-220, TO-220FP, TO-3

and D2PAK 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 employs internal current limiting,

thermal shut-down and safe area protection,

making it essentially indestructible. If adequate

heat sinking is provided, they can deliver over 1A

output current. Although designed
