and higher models. Sense is optional for 5 V
OUT
and lower.
e
All specifications are typical at nominal line voltage and full load, +25 deg.C. unless otherwise
noted. See detailed specifications.
f
Output capacitors are 1 μF ceramic || 10 μF electrolytic. Input cap is 22 μF, low ESR.
g
I/O caps are necessary for our test equipment and may not be needed for your application.
