AP2318A中文资料single-ldos数据手册Diodes规格书

描述 Description

The AP2318A is a series of ultra low dropout
regulators optimized for low voltage applications
where transient response and minimum input voltage
are critical.
The AP2318A provides current limit and thermal
shutdown function. Its circuit includes a trimmed
bandgap reference to assure output voltage accuracy to
be within ±1.5%. On-chip thermal shutdown provides
protection against any combination of overload and
ambient temperatures that would cause excessive
junction temperatures.
The AP2318A has adjustable version, which can set
the output voltage through two external resistors.

特性 Features

· Wide Operating Voltage Range: 2.5V to 12V

· PC Motherboard

简介

AP2318A属于集成电路（IC）的线性+开关稳压器。由制造生产的AP2318A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。
