TLE4275D中文资料汽车级线性稳压器数据手册Infineon规格书

描述 Description

The TLE4275 is a monolithic integrated low-drop voltage regulator in a 5-pin TO-package. An input voltage up to 45 V is regulated to V Q,nom = 5.0 V. The IC is able to drive loads up to 450 mA and is short-circuit proof. At over temperature the TLE4275 is turned off by the incorporated temperature protection. A reset signal is generated for an output voltage V Q,rt of typ. 4.65 V. The delay time can be programmed by the external delay capacitor.

简介

TLE4275D属于集成电路（IC）的线性+开关稳压器。由制造生产的TLE4275D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。
