BLOCK DIAGRAW
APPLICATIOU
Line and Load Regulation
U
W
U
Line regulation on the LT1019 is nearly perfect. A 10V
change in input voltage causes a typical output shift of less
than 5ppm. Load regulation (sourcing current) is nearly as
good. A 5mA change in load current shifts output voltage
by only 100
μ
V. These are electricaleffects, measured with
low duty cycle pulses to eliminate heating effects. In real
world applications, the thermaleffects of load and line
changes must be considered.
Two separate thermal effects are evident in monolithic
circuits. One is a gradient effect, where power dissipation
on the die creates temperature gradients. These gradients
can cause output voltage shifts even f the overall tempera-
ture coefficient of the reference s zero The LT1019, unlike
previous references, specifies thermal regulation caused
by die temperature gradients.The specification is
0.5ppm/mW. To calculate the effect on output voltage,
simply multiply the changein device power dissipation by
