IFX21401MB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 IFX21401 is a monolithic integrated low dropout voltage tracker in a tiny SMD package PG-SCT595-5 with excellent thermal resistance. It is designed to supply off-board loads (e.g. sensors) in harsh environments. The IC protects itself in case of overload, overtemperature, reverse polarity as well as output short circuit to battery or ground. Supply voltages up to V I = 45 V are regulated to a reference voltage applied at the adjust input “ADJ” with high accuracy. The output “Q” is able to drive loads up to 50 mA. In order to reduce the quiescent current to a minimum, the IFX21401 can be switched to stand-by mode by setting the adjust/enable input “ADJ/EN” to “low”.

简介

IFX21401MB属于集成电路（IC）的线性+开关稳压器。由制造生产的IFX21401MB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。
