MIC5249  
300mA µCap LDO with Programmable Power-On Reset Delay  
General Description  
Features  
The MIC5249 is an efficient, precise 300mA CMOS voltage  
regulator with power-on reset delay which can be imple-  
mentedviaanexternalcapacitor. Itoffers1%initialaccuracy,  
extremely-low-dropout voltage (typically 400mV @ 300mA),  
and low ground current (typically 85mA) over load.  
• 300mA output current  
• High PSRR: 65dB@120Hz  
• Stable with ceramic output capacitor  
• Power-on RESET output with adjustable delay time  
• High output accuracy:  
±1.0% initial accuracy  
±3.0% over temperature  
Designed specifically for noise-critical applications in hand-  
held or battery-powered devices, the MIC5249 comes  
equipped with a noise reduction feature to filter the output  
noiseviaanexternalcapacitor.OtherfeaturesoftheMIC5249  
include a logic compatible enable pin, current limit, thermal  
shutdown, ultra-fast transient response, and an active clamp  
to speed up device turnoff.  
• Low dropout voltage of 400mV @ 300mA  
• Low quiescent current: 85µA  
• Zero current shutdown mode  
• Thermal shutdown protection  
• Current-limit protection  
• Tiny MSOP-8 package  
The MIC5249 also works with low-ESR ceramic capacitors,  
reducing the amount of board space necessary for power  
applications, critical in hand-held wireless devices.  
Applications  
The MIC5249 is available in the MSOP-8 package.  
• Cellular phones  
• PDAs  
• Fiber optic modules
