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  
devices, the MIC5254 provides a TTL-logic-compatible  
enable pin. When disabled, power consumption drops  
nearly to zero.  
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  
10-pin MSOP 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 10-pin  
MSOP package and is rated over a –40°C to +125°C  
junction temperature range.  
Applications  
Cellular phones and pagers  
Cellular accessories
