The MIC23030 is a 400mA 8MHz switching regulator featuring HyperLight Load™ mode. The MIC23030 is highly efficient throughout the entire output current range, drawing just 21μA of quiescent current in operation. The tiny 1.6 x 1.6mm MLF® package, in combination with the 8MHz switching frequency, enables a compact sub-1mm height solution with only three external components. The MIC23030 provides accurate output voltage regulation under the most demanding conditions and responds extremely quickly to a load transient with exceptionally small output voltage ripple.
The MIC23030 operates from an input voltage range of 2.7V to 5.5V and features internal power MOSFETs that deliver up to 400mA of output current. This step-down regulator provides an output voltage accuracy of +/-2.5% across the junction temperature range of -40ºC to +125ºC. The MIC23030 is available in fixed or adjustable versions supporting an output voltage as low as 0.7V.
The MIC23030 evaluation board requires an input power source that is able to deliver greater than 500mA at 2.7V to the MIC23030. The output load can either be an active (electronic) or passive (resistive) load.
