描述 Description

TLE4263 is a 5-V low drop voltage regulator in a SMD package PG-DSO-14-30, PG-DSO-20-35, or G-DSO-8-16. The maximum input voltage is 45 V. The maximum output current is more than 200 mA. The IC is short-circuit proof and incorporates temperature protection which turns off the IC at overtemperature. The IC regulates an input voltage V I in the range of 6 V < V I < 45 V to V Q,nom = 5.0 V. A reset signal is generated for an output voltage of V Q,rt < 4.5 V. This voltage threshold can be decreased to 3.5 V by external connection of a voltage divider. The reset delay can be set externally by a capacitor. The integrated watchdog logic supervises the connected microcontroller. The IC can be switched off via the inhibit input, which causes the current consumption to drop from 900 μA to typical 0 μA.

简介

TLE4263属于集成电路（IC）的线性+开关稳压器。由Infineon制造生产的TLE4263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。
