? Dimensions are in inches (mm).
? These are partial model numbers. Please refer to the part number structure for complete ordering part numbers.
?? Vin must be 0.5V or higher than Vout.
?? Ripple and Noise is shown at Vout=1V.
? All specifications are at nominal line voltage, Vout=nominal (3.3V) and full load, +25 ?C. unless otherwise noted.
Output capacitors are 1 μF ceramic and 10 μF electrolytic in parallel. Input cap is 22 μF. See detailed specifications.
I/O caps are necessary for our test equipment and may not be needed for your application.

Product Label
Because of the small size of these products, the product label contains a
character-reduced code to indicate the model number and manufacturing date
code. Not all items on the label are always used. Please note that the label dif-
fers from the product photograph on page 1. Here is the layout of the label:
Input Voltage Range
2.4-5.5V
Model Number

The label contains three rows of information:
First row – Murata Power Solutions logo
First character – Last digit of manufacturing year, example 200 9
Second character – Month code (1 through 9 and O through D)
Third character – Day code (1 through 9 = 1 to 9, 10 = O and
11 through 31 = A through Z)
Fourth character – Manufacturing information
Second row – Model number product code (see table)
Third row – Manufacturing date code and revision level
