LD29300V80集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

LD29300V80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(tuán)制造生產(chǎn)的LD29300V80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。

Description

The LD29300 is a high current, high accuracy, low-dropout voltage regulator series. These regulators feature 400mV dropout voltage and very low ground current. Designed for high current loads, these devices are also used in lower current, extremely low dropout-critical systems, where their tiny dropout voltage and ground current values are important attributes.

Features

■ Very low dropout voltage (Typ. 0.4 at 3A)

■ Guaranteed output current up to 3A

■ Fixed voltage with ±1 tolerance at 25°C

■ Internal current and thermal limit

■ Logic controlled electronic shutdown available in PPAK
