描述 Description

The TLE 4266-2 is a monolithic integrated low-drop fixed voltage regulator which can supply loads up to 150 mA. It can be switched on and off by the INH pin. It is functional compatible to the TLE 4266, but with a reduced quiescent current of << 1 μ A in OFF mode and 40 μ A in ON mode. The TLE 4266-2 is especially designed for all applications that require very low quiescent current in ON and OFF mode. The device is available in the small surface mounted PG-SOT223-4 package. It is pin compatible to the TLE 4266 G. It is designed to supply microprocessor systems under the severe condition of automotive applications and therefore it is equipped with additional protection against over load, short circuit and overtemperature. Of course the TLE 4266-2 can be used in other applications, where a stabilized voltage and the inhibit feature is required. And input voltage VI up to 45 V is regulated to VQ = 5 V (TLE 4266-2 G) or VQ = 3.3 V (TLE 4266-2 GSV33) with an accuracy of ±3%. For the 5 V device an accuracy of ±2% is kept for a load current range? up to 50 mA. The device operates in the temperature range of T j = -40 to 150 °C. A high level at the INH pin switches the regulator on.

簡介

TLE4266-2G屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的TLE4266-2G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(gè)最小量，并且在工作時(shí)會(huì)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。
