TLE4275集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

TLE4275屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由英飛凌科技股份公司制造生產(chǎn)的TLE4275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。

Functional Description

The TLE 4275 is a monolithic integrated low-drop voltage regulator in a 5-pin TO-package. An input voltage up to 45 V is regulated to VQ,nom = 5.0 V. The IC is able to drive loads up to 450 mA and is short-circuit proof. At overtemperature the TLE 4275 is turned off by the incorporated temperature protection. A reset signal is generated for an output voltage VQ,rt of typ. 4.65 V. The delay time can be programmed by the external delay capacitor.
