TLE4279G数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The OPTIREG™ Linear TLE4279G is an automotive voltage regulator with a 5 V fixed output in a PG‑DSO‑8 package. The maximum operating voltage is 45 V. The output is able to drive a 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 < 4.65 V. The reset threshold voltage can be decreased by an external connection of a voltage divider. The reset delay time can be set by an external capacitor. If the application requires pull-up resistors at the logic outputs (reset, sense), the TLE4269G with integrated resistors can be used.It is also possible to supervise the input voltage by using an integrated comparator to give a low voltage warning.The TLE4279 is also available in a PG‑DSO‑14 package as TLE4279GM.

简介

TLE4279G属于集成电路（IC）的线性+开关稳压器。由制造生产的TLE4279G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。
