TLE4279GM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 TLE4279GM is an automotive voltage regulator with a 5 V fixed output in a PG‑DSO‑14 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 TLE4269GM 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‑8 package as TLE4279G.

简介

TLE4279GM属于集成电路（IC）的线性+开关稳压器。由制造生产的TLE4279GM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。
