描述 Description

The OPTIREG??Linear?TLE4269GL is an automotive voltage regulator with a 5?V fixed output in a PG?DSO?20 package. The maximum operating voltage is 45?V. The output is able to drive a 150?mA load. The device features short-circuit protection. The thermal shutdown feature switches the output off when the junction temperature exceeds 150°C to ensure the device is not damaged by overheating. A reset signal is generated when the output voltage drops below VQ?

簡介

TLE4269GL屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的TLE4269GL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(shí)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。
