Temperature Gradient Control
The S1F7661C0B0 offers a choice of three temperature
gradients which can be used to adjust the voltage regu-
lator output in applications such as power supplies for
driving LCDs.
Notes
1.
The definition of LOW for P
OFF
differs from that for TC1 and TC2.
2.
The temperature gradient affects the voltage between V
DD
and V
REG
.
