TLS715B0EJV50数据手册集成电路（IC）的稳压器-线性规格书PDF

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.

简介

TLS715B0EJV50属于集成电路（IC）的稳压器-线性。由制造生产的TLS715B0EJV50稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
