Infineon Technologies 英飞凌 TLF80511EJ LDO 线性固定电压调节器
英飞凌 TLF80511EJ LDO 线性固定电压调节器是一款线性低压差电压调节器，面向高达 400mA 的负载电流。TLF80511EJ 的典型静态电流为 38μA，是理想的解决方案，可用于要求工作电流非常低的系统，如永久连接电池的系统。它们具有非常低的压差，仅为 100mV，而输出电流小于 100mA。此外，压差区始于 3.3V 输入电压。这使得 TLF80511EJ 适合为汽车系统供电。此外，TLF80511 全新的快速调节概念只需一个 1μF 输出电容器即可保持稳定调节。它被设计用于汽车应用的严苛环境中。因此具有标准特性，如输出限流及过温关断。可避免输出接地短路、过流和过温等故障。
They feature a very low dropout voltage of 100mV, when the output current is less than 100mA. In addition, the dropout region begins at input voltages of 3.3V. This makes the TLF80511EJ suitable to supply automotive systems. In addition, the TLF80511's new fast regulation concept requires only a single, 1μF output capacitor to maintain stable regulation. It is designed for the harsh environment of automotive applications. Therefore standard features like output current limitation and overtemperature shutdown are implemented. They protect the device against failures like output short circuit to GND, over-current and over-temperatures.
