150mA  
µCap CMOS LDO Regulator w/Power Good  
Final Information  
General Description  
Features  
The MIC5248 is an efficient, precise CMOS voltage regulator  
with power good output. The MIC5248 offers better than 3%  
initialaccuracy,andconstantgroundcurrent(typically100µA)  
over load.  
• Power Good indicator  
• Load independent, ultra-low ground current: 100µA  
• 150mA output current  
• Current limiting  
• Thermal shutdown  
• Tight load and line regulation  
• “Zero” off-mode current  
• Stability with low-ESR capacitors  
• Fast transient response  
• TTL-logic-controlled enable input  
The MIC5248 also works with low-ESR ceramic capacitors,  
reducing the amount of board space necessary for power  
applications, critical in handheld wireless devices.  
Key features include current limit, thermal shutdown, a push-  
pull output for faster transient response, and an active clamp  
tospeedupdeviceturnoff.AvailableintheIttyBittySOT-23-5  
package, the MIC5248 is a fixed 1.2V regulator.  
Applications  
• Processor power-up sequencing  
• Laptop, notebook, and palmtop computers  
• PCMCIA V and V regulation/switching
