L7818CV-DG集成电路（IC）的线性+开关稳压器规格书PDF中文资料

L7818CV-DG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L7818CV-DG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。

描述 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 shutdown 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.

特性 Features
