MIC3385  
8MHz Inductorless Buck Regulator  
with LDO Standby Mode  
General Description  
The Micrel MIC3385 is a high-efficiency inductorless buck  
regulator that features a LOWQ® LDO standby mode that  
draws only 18µA of quiescent current. The MIC3385  
requires no external inductor enabling an ultra-low noise,  
small size, and high efficiency solution for portable power  
applications.  
LOWQ®  
Features  
• 2.7 to 5.5V supply voltage  
• Light load LOWQ® LDO mode  
In PWM mode, the MIC3385 operates with a constant  
frequency 8MHz PWM control. Under light load conditions,  
such as in system sleep or standby modes, the PWM  
switching operation can be disabled to reduce switching  
losses. In this light load LOWQ® mode, the LDO maintains  
the output voltage and draws only 18µA of quiescent  
current. The LDO mode of operation saves battery life  
while not introducing spurious noise and high ripple as  
experienced with pulse skipping or bursting mode  
regulators.

• Adjustable output voltage option down to 1V  
• Ultra-fast transient response  
• No external inductor required  
• Enables sub 1mm profile solution  
• Fully integrated MOSFET switches  
• Micropower shutdown  
• Thermal shutdown and current limit protection  
• Pb-free 14-pin 3x3.5x0.9mm MLF® package  
• –40°C to +125°C junction temperature range  
The MIC3385 operates from 2.7V to 5.5V input and  
features internal power MOSFETs that can supply up to  
600mA output current in PWM mode. It can operate with a  
maximum duty cycle of 100% for use in low-dropout  
conditions.  
The MIC3385 is available in the 14-pin 3mm x 3.5mm  
MLF® package with a junction operating range from –40°C  
to +125°C.
