AP7335中文资料single-ldos数据手册Diodes规格书

描述 Description

The AP7335 is a 300mA, adjustable and fixed output voltage,
low dropout linear regulator. The device included 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 approximately 35μA. Built-in current-limit and
thermal-shutdown functions prevent IC from damage in fault
conditions.
This device is available with adjustable output from 0.8V to
5.0V, and fixed version with 0.8V, 1.0V, 1.2V, 1.5V, 1.8V,
2.0V, 2.5V, 2.8V, 3.0V, 3.3V and 3.9V outputs. Please
contact your local sales office for any other voltage options.
The AP7335 is available in SOT25 and DFN2020-6
packages.

简介

AP7335属于集成电路（IC）的线性+开关稳压器。由制造生产的AP7335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。
