L5050SD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 L5050SD is a dual isolated 5V low dropout linear voltage regulator suitable for automotive applications, available in a SO-8 package. The LDO delivers up to 2x50 mA of load current, and consumes as low as 5 µA per each output of quiescent current with device disabled. High output voltage accuracy (±2%) is kept over wide temperature range, line and load variation. Enable features allow enabling or disabling each output. The maximum input voltage is 40 V. The regulator output current is internally limited and the device is protected against short circuit, overload and over temperature conditions. In addition, only low value ceramic capacitor on output is required for stability.

简介

L5050SD属于集成电路（IC）的线性+开关稳压器。由制造生产的L5050SD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。
