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  
implemented via an external capacitor. It offers 1% initial  
accuracy, 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  
noise via an external capacitor. Other features of the  
MIC5249 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  
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.  
Tiny MSOP-8 package  
Applications  
The MIC5249 is available in the MSOP-8 package.  
Cellular phones  
PDAs  
Fiber optic modules
