AP7168中文资料single-ldos数据手册Diodes规格书

描述 Description

The AP7168 is a 1.2A, adjustable output voltage, ultra-low
dropout linear regulator. The device includes pass element, error
amplifier, band-gap reference, current limit and thermal shutdown
circuitry. The device is turned on when EN pin is set to logic high
level. A Power-OK (POK) output is available for power sequence
control.
The characteristics of the low dropout voltage and low quiescent
current make it suitable for low to medium power applications, for
example, laptop computers, audio and video applications, and
battery powered devices. The typical quiescent current is
approximately 125μA.
Built-in current-limit and thermal-shutdown functions prevent
IC from damage in fault conditions. The AP7168 is available in
SO-8EP package.

简介

AP7168属于集成电路（IC）的线性+开关稳压器。由制造生产的AP7168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。
