AP7347D集成电路（IC）的线性+开关稳压器规格书PDF中文资料

AP7347D属于集成电路（IC）的线性+开关稳压器。由美台半导体制造生产的AP7347D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。

描述 Description

The AP7347D is a low-dropout regulator with high output voltage

accuracy, low RDS(on), high PSRR, low output noise, and low quiescent

current. This regulator is based on a CMOS process.

The AP7347D includes a voltage reference, error amplifier, currentlimit circuit, and an enable input to turn it on and off. With the integrated

resistor network, fixed output voltage versions can be delivered.

With its low power consumption and line and load transient response,

the AP7347D is well-suited for noise sensitive automotive equipment.

The AP7347D is packaged in the SOT25 (Type A1) and W-DFN2020-

6 (SWP) (Type A1) (wettable) packages, which allow for the smallest

footprint and a dense PCB layout.
