TLE4252D集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLE4252D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TLE4252D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。

Short Functional Description

The TLE 4252 is a monolithic integrated low-drop voltage tracking regulator in a very small SMD package P-TO252-5-1. It is designed to supply off-board systems, e.g. sensors in engine management systems under the severe conditions of automotive applications. Therefore the device is equipped with additional protection functions against reverse polarity and short circuit to GND and battery.
