描述 Description

The TLS850B0TEV50 is a high performance, very low dropout linear voltage regulator for 5.0 V supply in a PGTO252-5 package. The input voltage range of 3 V to 40 V and a very low quiescent current of 20 μA make it the perfect match for automotive or other supply systems connected to the battery permanently. The new loop concept combines fast regulation and very high stability. Below an output current of 100 mA the typical dropout voltage is below 100mV. The operating range starts at an input voltage of only 3 V (extended operating range). This makes the TLS850B0TEV50 suitable for automotive systems that need to operate during cranking condition. The device can be switched on and off by the Enable feature. Internal protection features such as output current limitation and overtemperature shutdown protect the device from immediate damage due to failures such as output shorted to GND, overcurrent and overtemperature.

簡介

TLS850B0TEV50屬于集成電路（IC）的線性+開關穩(wěn)壓器。由制造生產(chǎn)的TLS850B0TEV50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。
