All specifications are at nominal line voltage and full load, +25 deg.C. unless otherwise noted. See
detailed specifications.
Output capacitors are 1 μF ceramic in parallel with 10 μF electrolytic. Input cap is 22 μF, low ESR.
These I/O caps are necessary for our test equipment and may not be needed for your application.
e
Sense input is not included for 12 Vout and higher models. Sense is optional for 5 Vout and lower.
