L7805CV-DG屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由意法半導(dǎo)體集團制造生產(chǎn)的L7805CV-DG穩(wěn)壓器 - 線性線性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無論負(fù)載電流、輸入電壓或環(huán)境因素如何變化，這些輸出電壓通常都要保持不變。它們的工作原理要求輸入電壓維持在高于所需的輸出電壓，而且要超出某個最小量，并且在工作時會將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開關(guān)模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應(yīng)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

? Output current up to 1.5 A
