AP2202中文资料single-ldos数据手册Diodes规格书

描述 Description

The AP2202 is a 150mA ULDO regulator which provides
very low noise, ultra low dropout voltage
(typically 165mV at 150mA), very low standby current
(1μA maximum) and excellent power supply ripple
rejection (PSRR 75dB at 100Hz) in battery powered
applications, such as handsets and PDAs and in noise
sensitive applications, such as RF electronics.
The AP2202 also features logic compatible enable/
shutdown control inputs, a low power shutdown mode
for extended battery life, over current protection, over
temperature protection, as well as reversed-battery protection.
The AP2202 has adjustable, 2.5V, 2.6V, 2.8V, 3.0V and
3.3V versions.
The AP2202 is available in space saving SOT-23-5 and
SOT-89 packages.

简介

AP2202属于集成电路（IC）的线性+开关稳压器。由Diodes制造生产的AP2202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。
