Figure 28. Battery Backed−Up Power Supply
Figure 29. Adjusting Output of Fixed
Voltage Regulators
The 50
W resistor that is in series with the ground pin of the
upper regulator level shifts its output 300 mV higher than the
lower regulator. This keeps the lower regulator off until the
input source is removed.
Resistor R2 sets the maximum output voltage. Each
transistor reduces the output voltage when turned on.
