MIC5250  
Dual 150mA µCap CMOS LDO Regulator  
Preliminary Information  
General Description  
Features  
The MIC5250 is an efficient, precise dual CMOS voltage  
regulator optimized for ultra-low-noise applications. The  
MIC5250offersbetterthan1%initialaccuracy,extremelylow  
dropout voltage (typically 150mV at 150mA) and constant  
ground current over load (typically 100µA). The MIC5250  
provides a very-low-noise output, ideal for RF applications  
where quiet voltage sources are required. A noise bypass pin  
is also available for further reduction of output noise.  
• Ultralow dropout—100mV @ 100mA  
• Ultralow noise—30µV(rms)  
• Stability with ceramic, tantalum, or aluminum electrolytic  
capacitors  
• Load independent, ultralow ground current  
• 150mA output current  
• Current limiting  
• Thermal Shutdown  
• Tight load and line regulation  
• “Zero” off-mode current  
• Fast transient response  
Designed specifically for hand-held and battery-powered  
devices, the MIC5250 provides TTL logic compatible enable  
pins. When disabled, power consumption drops nearly to  
zero.  
• TTL-Logic-controlled enable input  
Applications  
• Cellular phones and pagers  
• Cellular accessories  
The MIC5250 also works with low-ESR ceramic capacitors,  
reducing the amount of board space necessary for power  
applications, critical in hand-held wireless devices.  
Key features include current limit, thermal shutdown, push-  
pull outputs for faster transient response, and active clamps  
to speed up device turnoff. Available in the 10-lead MSOP  
(micro-shrink-outline package), the MIC5250 also offers a  
range of fixed output voltages.  
• Battery-powered equipment  
• Laptop, notebook, and palmtop computers  
• PCMCIA V and V regulation/switching  
CC  
PP  
• Consumer/personal electronics  
• SMPS post-regulator/dc-to-dc modules  
• High-efficiency linear power supplies
