MIC94310  
200mA LDO with  
Ripple BlockerTechnology  
General Description  
Features  
The MIC94310 Ripple Blocker™ is 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  
MIC94310 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 10MHz at 200mA load  
Rated to 200mA output current  
Fixed output voltages  
Current-limit and thermal-limit protected  
Ultra-small 0.88mm x 0.88mm 4-ball CSP  
1.2mm x 1.6mm, 4-pin Thin MLF®  
Logic-controlled enable pin  
• −40°C to +125°C junction temperature range  
The MIC94310 operates from an input voltage of 1.8V to  
3.6V.  
Applications  
Packaged in a 0.88mm x 0.88mm 4-ball CSP or a 4-pin  
1.2mm x 1.6mm Thin MLF®, the MIC94310 has a junction  
operating temperature range of –40°C to +125°C.
