LDF33DT-TR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 LDF is a fast, very low drop linear regulator which operates from an input supplyvoltage in the range of 2.6 V to 16 V.
It is available in fixed and adjustable output voltage versions, from 0.8 V to 12 V.
The LDF features are: high output precision, very low-dropout voltage, low noise, and lowquiescent current, therefore suitable for low voltage microprocessors and memoryapplications.
Enable logic control pin and power-good output are featured on PPAK/DFN packages.
Current and thermal protection are provided.

简介

LDF33DT-TR属于集成电路（IC）的线性+开关稳压器。由制造生产的LDF33DT-TR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。
