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.

Features

? Output current up to 1.5 A

? Output voltages of 5; 6; 8; 8.5; 9; 12; 15; 18; 24 V

? Thermal overload protection

? Short circuit protection

? Output transition SOA protection

? 2 output voltage tolerance (A version)

? Guaranteed in extended temperature range (A version)

L7808CV-DG屬于集成電路（IC） > 線性 + 開關(guān)穩(wěn)壓器。意法半導(dǎo)體（ST）集團(tuán)制造生產(chǎn)的L7808CV-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(wú)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(gè)最小量，并且在工作時(shí)會(huì)將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對(duì)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(duì)噪聲高度敏感的應(yīng)用。
