MIC5312  
LowQTM Mode Dual 300mA LDO  
with Integrated POR  
General Description  
Features  
Input voltage range: 2.5V to 5.5V  
The MIC5312 is a high performance, dual µCap low  
dropout regulator with integrated power-on reset  
supervisor, offering ultra-low operating current and a  
LowQTM Mode  
-
-
-
7µA total quiescent current  
10mA output current capable LowQTM mode  
Logic level control with external pin  
second, even lower operating current mode, LowQTM  
mode, reducing operating current by 75%. Each  
regulator can source up to 300mA of output current  
maximum.  
Stable with ceramic output capacitor  
2 LDO Outputs – 300mA each  
Integrated Power-on Reset (POR) with adjustable  
Ideal for battery operated applications, the MIC5312  
offers 1% accuracy, extremely low dropout voltage  
(60mV @ 150mA), and low ground current (typically  
delay time  
Tiny 3mm x 3mm MLF™-10 package  
Low dropout voltage of 60mV @ 150mA  
28µA total). When put into LowQTM mode, the internal  
current draw drops down to 7µA total. The MIC5312  
also comes equipped with a TTL logic compatible  
enable pin that allows the part to be put into a zero-off-  
mode current state, drawing no current when disabled.  
Ultra-low quiescent current of 28µA total in Full  
Current Mode  
High output accuracy  
-
-
±1.0% initial accuracy  
±2.0% over temperature  
The Power-on Reset is active low and indicates an  
output undervoltage condition on either regulator 1 or 2  
when the regulator is enabled.  
Thermal Shutdown Protection  
Current Limit Protection  
Applications  
The MIC5312 is a µCap design, operating with very  
small ceramic output capacitors for stability, reducing  
required board space and component cost.  
Cellular/PCS phones  
Wireless modems  
PDAs  
The MIC5312 is available in fixed output voltages in the  
3mm x 3mm MLF-10 leadless package. Data sheets  
and support documentation can be found on Micrel’s
