描述 Description

The TLF80511TC is a linear low dropout voltage regulator for load currents up to 400 mA in D2PAK,? DPAK and DSO8-EP packages with fixed output voltage (5V and 3.3V). An input voltage of up to 40 V is regulated to V Q,nom? = 5 V with ±2 % precision. The? TLF80511TC? with? a? typical? quiescent? current? of? 38 μA,? is? the? ideal? solution? for? systems? requiring? very? low operating currents, such as those permanently connected to a battery. It features a very low dropout voltage of 100 mV, when the output current is less than 100 mA. In addition, the dropout region begins at input voltages of 3.3 V (extended operating range). This makes the TLF80511 suitable to supply automotive systems. In addition, the TLF80511TC’s new fast regulation concept requires only a single, 1 μF output capacitor to maintain stable regulation.

簡介

TLF80511TC屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的TLF80511TC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。
