描述 Description

The TLS805B1 is a linear voltage regulator featuring wide input voltage range, low dropout voltage and ultra low quiescent current. With an input voltage range of 2.75 V to 42 V and ultra low quiescent of only 5 μA, the regulator is perfectly suitable for automotive or any other supply systems connected permanently to the battery. The TLS805B1SJ/LDV is the adjustable output version with an accuracy of 2% and output current capability up to 50 mA. The new regulation concept implemented in TLS805B1 combines fast regulation and very good stability while requiring only a small ceramic capacitor of 1 μF at the output. The tracking region starts already at input voltages of 2.75 V (extended operating range). This makes the TLS805B1 also suitable to supply automotive systems that need to operate during cranking condition. Internal protection features like output current limitation and overtemperature shutdown are implemented to protect the device against immediate damage due to failures like output short circuit to GND, over-current and over-temperature. The device can be switched on and off by the Enable feature. When the device is switched off, the current consumption is typically less than 1 μA.

簡介

TLS805B1LDV屬于集成電路（IC）的線性+開關穩(wěn)壓器。由制造生產的TLS805B1LDV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。
