TLE4279集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLE4279属于集成电路（IC）的线性+开关稳压器。由英飞凌科技股份公司制造生产的TLE4279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。

描述 Description

The OPTIREG™ Linear TLE4279 is an automotive voltage regulator with a 5 V fixed output, in a PG-DSO-8 or PG-DSO-14 package. The maximum operating voltage is 45 V. The output is able to drive 150 mA load. The device features short-circuit protection. The thermal shutdown feature switches the output off when the junction temperature exceeds 150°C to ensure the device is not damaged by overheating. A reset signal is generated when the output voltage drops below VQ
