TLE42694G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TLE42694G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 TLE 42694 is a monolithic integrated low dropout voltage regulator, especially designed for automotive applications. An input voltage up to 45 V is regulated to an output voltage of 5.0 V. The component is able to drive loads up to 150 mA. It is short-circuit proof by the implemented output current limitation and has an integrated overtemperature shutdown. A reset signal is generated for an output voltage VQ,rt of typically 4.65 V. This threshold can be decreased by an external resistor divider.
