Application Note
OUTPUT VOLTAGE
The adjustable version develops at 1.25V reference voltage,
(V
), between the output and the adjust terminal. As
shown in
Figure 1
, this voltage is applied across resistor R1
to generate a constant current I1. This constant current then
flows through R2. The resulting voltage drop across R2 adds
to the reference voltage to sets the desired output voltage.
The current I
ADJ
from the adjustment terminal introduces an
output error. But since it is small (120μA max), it becomes
negligible when R1 is in the 100
range.
For fixed voltage devices, R1 and R2 are integrated inside
the devices.
