MIC5254  
Dual 150mA µCap LDO with Error Flag Outputs  
General Description  
Features  
The MIC5254 is an efficient, precise, dual CMOS voltage  
regulator. It offers better than 1% initial accuracy, extremely  
low dropout voltage (typically 135mV at 150mA) and low  
ground current (typically 90µA) over load. The MIC5254  
features two independent LDOs with error flags that indicate  
an output fault condition such as overcurrent, thermal shut-  
down and dropout.  
• Input voltage range: 2.7V to 6.0V  
• Dual, independent 150mA LDOs  
• Error flags indicate fault condition  
• Stable with ceramic output capacitor  
• Ultra-low dropout: 135mV @ 150mA  
• High output accuracy:  
1.0% initial accuracy  
2.0% over temperature  
Designed specifically for handheld and battery-powered de-  
vices, the MIC5254 provides a TTL-logic-compatible enable  
pin.Whendisabled,powerconsumptiondropsnearlytozero.  
• Low quiescent current: 90µA each LDO  
• Tight load and line regulation  
• Thermal shutdown and current limit protection  
• “Zero” off-mode current  
• TTL logic-controlled enable input  
• MSOP-10 package  
The MIC5254 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, faster  
transient response, and an active clamp to speed up device  
turnoff. The MIC5254 is available in the MSOP-10 package  
and is rated over a –40°C to +125°C junction temperature  
range.  
Applications  
• Cellular phones and pagers  
• Cellular accessories  
• Battery-powered equipment  
• Laptop, notebook, and palmtop computers  
• Consumer/personal electronics
