描述 Description

The TLS715B0 is a low dropout linear voltage regulator for load current up to 150 mA. An input voltage of up to 40 V is regulated to VQ,nom = 5 V with ± 2 % precision. The TLS715B0, with a typical quiescent current of 36 μA, is the ideal solution for systems requiring very low operating current, such as those permanently connected to the battery. It features a very low dropout voltage of 200 mV, when the output current is less than 100 mA. In addition, the dropout region begins at input voltages of 4.0 V (extended operating range). This makes the TLS715B0 suitable to supply automotive systems with start-stop requirements. The device can be switched on and off by the enable feature. In addition, the TLS715B0’s new fast regulation concept requires only a single 1 μF output capacitor to maintain stable regulation. The device is designed for the harsh environment of automotive applications. Therefore standard features like output current limitation and overtemperature shutdown are implemented and protect the device against failures like output short circuit to GND, overcurrent and overtemperature. The TLS715B0 can be also used in all other applications requiring a stabilized 5 V supply voltage.

簡介

TLS715B0EJV50屬于集成電路（IC）的穩(wěn)壓器-線性。由制造生產的TLS715B0EJV50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。
