TLE4699E中文资料汽车级线性稳压器数据手册Infineon规格书

描述 Description

The integrated reset as well as several protection circuits, combined with a wide operating temperature range offered by the TLE4699 make it suitable for supplying microprocessor systems in automotive environments. The early warning function supervises the voltage at pin SI. Modifying the reset threshold is possible by an optional resistor divider. The TLE4699 is available in a PG-DSO-14 package which makes it pin-compatible to the TLE4299 as well as in a small thermally enhanced PG-SSOP-14 EP exposed pad package.

简介

TLE4699E属于集成电路（IC）的线性+开关稳压器。由Infineon制造生产的TLE4699E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。
