Regulated –5V Output Voltage
Figure 12 shows a regulated –5V output with a 9V input.
With a 0mA to 5mA load current, the R
OUT
is below 20Ω.
Paralleling for Lower Output Resistance
Additional
flexibility of the LTC1144 is shown in Figure 13.
Tw o LTC1144s are connected in parallel to provide a lower
effective output resistance. However, if the output resis
-
tance is dominated by 1/(f ×
C1), increasing the capacitor
size (C1) or increasing the frequency will be of more benefit
than the paralleling circuit shown.
