描述 Description

The AP2318 is a series of ultra low dropout regulators
optimized for low voltage applications where transient
response and minimum input voltage are critical.
The AP2318 provides current limit and thermal
shutdown. 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 create excessive
junction temperatures.
The AP2318 has both fixed and adjustable versions.
The 1.3V fixed versions integrate the corresponding
resistor divider. The adjustable version can set the
output voltage through two external resistors.

简介

AP2318属于集成电路（IC）的线性+开关稳压器。由制造生产的AP2318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。
