TLE42764集成電路（IC）的線性+開關穩(wěn)壓器規(guī)格書PDF中文資料

TLE42764屬于集成電路（IC）的線性+開關穩(wěn)壓器。由英飛凌科技股份公司制造生產的TLE42764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換為熱量。對于大多數(shù)應用而言，雖然這種穩(wěn)壓器的效率低于開關模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應用。

Description

The TLE42764 is a monolithic integrated low dropout voltage regulator for load currents up to 400 mA. An input voltage up to 40 V is regulated to an adjustable or 5 V fixed voltage with a precision of ±2. The device is designed for the harsh environment of automotive applications. Therefore it is protected against overload, short circuit and overtemperature conditions by the implemented output current limitation and the overtemperature shutdown circuit. The TLE42764 can be also used in all other applications requiring a stabilized voltage between 2.5 V and 20 V.

Due to its very low quiescent current the TLE42764 is dedicated for use in applications permanently connected to VBAT. In addition the device can be switched off via the Enable input reducing the current consumption to less than 10 μA.
