AP2213数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The AP2213 is a 500mA output current fixed voltage
regulator which provides low noise, very low dropout
voltage (typically 350mV at 500mA), 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 AP2213 features individual 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 AP2213 has 2.5V, 3.0V and 3.3V versions.
