Datasheet
PART NUMBER STRUCTURE
➀ For Vout ≥ 3.3V, Vin should be ≥ (Vout ÷ 0.85) + 0.5V.
➁ Ripple and Noise is shown at Vout=1V. See specs for details.
➂ All specifi cations are at nominal line voltage, Vout= 5V and full load, +25°C. unless other-
wise noted. Output capacitors are 1 µF ceramic and 22 µF electrolytic in parallel. Input cap
is 22 µF. See detailed specifi cations. 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:
The label contains three rows of information:
First row – Murata Power Solutions logo
Second row – Model number product code (see table)
Third row – Manufacturing date code and revision level
The manufacturing date code is four characters:
First character – Last digit of manufacturing year, example 2009
Second character – Month code (1 through 9 = Jan-Sep;
O, N, D = Oct, Nov, Dec)
Third character – Day code (1 through 9 = 1 to 9, 10 = 0 and
11 through 31 = A through Z)
Fourth character – Manufacturing information
