AP7315中文资料150mA HIGH PSRR LOW NOISE LDO WITH ENABLE数据手册Diodes规格书

描述 Description

The AP7315 is a low dropout regulator with high output voltage accuracy, low RDSON, high PSRR, low output noise and low quiescent current. This regulator is based on a CMOS process.
The AP7315 includes a voltage reference, error amplifier, current limit 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 AP7315 is well suited for low power handheld communication equipment.
The AP7315 is packaged in an X2-DFN1010-4, SOT23 and SOT25 package and allows for smallest footprint and dense PCB layout.

简介

AP7315属于集成电路（IC）的线性+开关稳压器。由制造生产的AP7315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。
