TLE42644G中文资料汽车级线性稳压器数据手册Infineon规格书

描述 Description

It is functional compatible to the TLE4264, but has a reduced quiescent current of typ. 40µA. The TLE42644 is especially designed for applications requiring very low standby currents, e.g. with a permanent connection to the car’s battery. The device is available in the small surface mounted PG-SOT223-4 package and is pin compatible to the TLE4264-2 and the TLE4264. The device is designed for the harsh environment of automotive applications. Therefore it is protected against overload, short circuit and overtemperature conditions by the implemented output current limitation and the overtemperature shutdown circuit. The TLE42644 can be also used in all other applications requiring a stabilized 5 V voltage. An input voltage up to 45 V is regulated to V Q,nom = 5 V with a precision of ±3 %. An accuracy of ±2 % is kept for load currents up to 50 mA.

简介

TLE42644G属于集成电路（IC）的线性+开关稳压器。由制造生产的TLE42644G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。
