描述 Description

The TLS850D0TEV33 is a high performance very low dropout linear voltage regulator for 3.3 V supply in a PG-TO252-5 package. With an input voltage range of 3 V to 40 V and very low quiescent of only 40 μA, these regulators are perfectly suitable for automotive or any other supply systems connected to the battery permanently. The TLS850D0TAV33 provides an output voltage accuracy of 2 % and a maximum output current up to 500 mA. The new loop concept combines fast regulation and very good stability while requiring only one small ceramic capacitor of 1 μF at the output. At currents below 100 mA the device will have a very low typical dropout voltage of only 80 mV. The operating range starts already at input voltages of only 3 V (extended operating range). This makes the TLS850D0TAV33 also suitable to supply automotive systems that need to operate during cranking condition.

簡介

TLS850D0TEV33屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的TLS850D0TEV33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。
