MIC94325/45/55  
500mA LDO with  
Ripple BlockerTechnology  
General Description  
Features  
The MIC943x5 Ripple Blockeris a monolithic integrated  
circuit that provides low-frequency ripple attenuation  
(switching noise rejection) to a regulated output voltage.  
This is important for applications where a DC/DC switching  
converter is required to lower or raise a battery voltage but  
where switching noise cannot be tolerated by sensitive  
downstream circuits such as in RF applications. The  
MIC943x5 maintains high power supply ripple rejection  
(PSRR) with input voltages operating near the output  
voltage level to improve overall system efficiency. A low-  
voltage logic enable pin facilitates ON/OFF control at  
typical GPIO voltage levels.  
1.8V to 3.6V input voltage range  
Active noise rejection over a wide frequency band  
>50dB from 10Hz to 5MHz at 500mA load  
Rated to 500mA output current  
Fixed and adjustable output voltages  
Optional output auto-discharge when disabled  
Current-limit and thermal-limit protected  
Ultra-small 0.84mm x 1.32mm 6-ball CSP  
1.6mm x 1.6mm, 6-pin Thin DFN  
Logic-controlled enable pin  
The MIC943x5 operates from an input voltage of 1.8V to  
3.6V. The MIC943x5 options include fixed (MIC94345/55)  
or adjustable (MIC94325) output voltages. The MIC94355  
version offers an auto-discharge to discharge the output  
capacitor when the part is disabled.  
 40C to +125C junction temperature range  
Applications  
Smart phones  
Packaged in a 0.84mm x 1.32mm 6-ball CSP or a 6-pin  
1.6mm x 1.6mm Thin DFN, the MIC943x5 has a junction  
operating temperature range of –40C to +125C.
