TLF80511TC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 TLF80511TC is a linear low dropout voltage regulator for load currents up to 400 mA in D²PAK,  DPAK and DSO8-EP packages with fixed output voltage (5V and 3.3V). An input voltage of up to 40 V is regulated to V Q,nom  = 5 V with ±2 % precision. The  TLF80511TC  with  a  typical  quiescent  current  of  38 µA,  is  the  ideal  solution  for  systems  requiring  very  low operating currents, such as those permanently connected to a battery. It features a very low dropout voltage of 100 mV, when the output current is less than 100 mA. In addition, the dropout region begins at input voltages of 3.3 V (extended operating range). This makes the TLF80511 suitable to supply automotive systems. In addition, the TLF80511TC’s new fast regulation concept requires only a single, 1 µF output capacitor to maintain stable regulation.

简介

TLF80511TC属于集成电路（IC）的线性+开关稳压器。由制造生产的TLF80511TC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。
