AP7335A-50中文资料300mA, LOW QUIESCENT CURRENT, FAST TRANSIENT LOW DROPOUT LINEAR REGULATOR数据手册Diodes规格书

描述 Description

The AP7335A-50 is a 300mA, 5.0V fixed output voltage, low-dropout linear regulator with ±1% output voltage accuracy. The device includes pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry. The device is turned on when EN pin is set to logic high level.
The characteristics of low-dropout voltage and low-quiescent current make it suitable for low-power applications, for example, battery powered devices. The typical quiescent current is 35μA. Built-in, current-limit and thermal-shutdown functions prevent IC from damage in fault conditions.
This device is only available as a 5.0V fixed version. Please contact your local sales office for any other voltage options.
The AP7335A-50 is packaged in SOT25 and U-DFN2020-6.

简介

AP7335A-50属于集成电路（IC）的线性+开关稳压器。由制造生产的AP7335A-50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。
