3.3.3 Static
Regulation
The output voltages shall remain within limits specified in Dynamic Regulation for the step
loading and capacitive loading specified in below table. The dynamic tolerance includes the
static regulation tolerance. The load transient repetition rate shall be tested between 50 Hz and
5 kHz at duty ranging from 10% to 90%. The load transient repetition rate is only a test
specification. The ∆step load may occur anywhere within the Min load to Max load conditions.
