PART NUMBER STRUCTURE
➀ Dimensions are in inches (mm).
➁ These are partial model numbers. Please refer to the part number structure for complete ordering part numbers.
➂ All specifications are at nominal line voltage, Vout=nominal (5V for D12 models) 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 specifica-
tions.
I/O caps are necessary for our test equipment and may not be needed for your application.
Vin must be 2V or higher than Vout for 3.3 to 5V outputs.
Ripple and Noise is shown at Vout=1V. See specs for details.
➅Max. V
OUT = 5.1V at IOUT = 5A.
➆Max. VOUT = 5.1V at IOUT = 3A.
