TLE4284集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLE4284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TLE4284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。

Functional Description

The TLE 4284 is a monolithic integrated fixed or adjustable NPN type voltage regulator that can supply loads up to 800 mA. The device is housed in the surface mounted P-TO252-3-1 package (D-Pak). It is designed to supply microprocessor systems under the severe conditions of automotive applications and therefore it is equipped with additional protection against over load, short circuit and overtemperature.
