5) Verify that the output voltage (measured at the V
OUT1
and V
OUT2
pins re-
spectively) has the desired value.
6) Table 2–4 shows the three recommended options for loading each regula-
tor.

JP5–Regulator 1
JP6–Regulator 2
SW_1 External Load
Continuous load off-board Open Off Connected
Continuous load onboard Shorted On/off Not connected
Pulsed load onboard
Open On Not connected
Jumpers JP7 – JP11 and JP12 – JP16 vary the current through the onboard
resistors from 0 to max load current for regulator 1 and regulator 2 respectively.
Simultaneous and continuous operation of both regulator outputs at full
load may exceed the power dissipation rating of the PWP package. For
more information, refer to the thermal information section in the
TPS703xx data sheet (literature number SLVS285).
