描述 Description

The AP7176B is a 3.0A ultra low-dropout (LDO) linear regulator that features an enable input and a power-good output. The enable input and power-good output allow users to configure power management solutions that can meet the sequencing requirements of FPGAs, DSPs, and other applications with different start-up and power-down requirements. The AP7176B features two supply inputs, for power conversion supply and control. With the separation of the control and the power input very low dropout voltages can be reached and power dissipation is reduced. A precision reference and feedback control deliver 1.5% accuracy over load, line, and operating temperature ranges. The AP7176B is available in SO-8EP and MSOP-8EP package with an exposed PAD to reduce the junction to case resistance and extend the temperature range it can be used in.

简介

AP7176B属于集成电路（IC）的线性+开关稳压器。由制造生产的AP7176B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。
