PRINTED CIRCUIT BOARD and LAYOUT
CONSIDERATIONS
The LM4030 has a very small change in reverse voltage with
current (25ppm/mA typical) so large variations in load current
(up to 50mA) should not appreciably shift VREF. Parasitic re-
sistance between the LM4030 and the load introduces a
11
voltage drop proportional to load current and should be min-
imized. The LM4030 should be placed as close to the load it
is driving as the layout will allow. The location of R
important, but C
possible so added ESR does not degrade the transient per-
formance.
OUT
