Regulating V
OUT
It is possible to regulate the output of the LM2681 by use of
a low dropout regulator (such as LP2980-5.0). The whole
converter is depicted in Figure 5.
A different output voltage is possible by use of LP2980-3.3,
LP2980-3.0, or LP2980-adj.
Note that, the following conditions must be satisfied simulta-
neously for worst case design:
2V
in_min
>V
out_min +Vdrop_max (LP2980) + Iout_max xRout_max (LM2681)
2V
in_max < Vout_max +Vdrop_min (LP2980) + Iout_min xRout_min (LM2681)
