The MIC2225 is a dual output regulator featuring a high efficiency 2MHz PWM synchronous buck (step-down) regulator and a 300mA LDO. The MIC2225 is an ultra-low noise, small size, and high efficiency solution for portable power applications, providing core and I/O supply rails for applications like application processors, camera DSPs and multimedia chipsets.In PWM mode, the MIC2225 operates with a constant 2MHz frequency. The MIC2225 switching regulator operates from 2.7V to 5.5V input and features internal power MOSFETs that can supply up to 600mA output current in PWM mode.
