Overview

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.
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...
