Application Hints
In operation, the LM138 develops a nominal 1.25V reference
voltage, V
The reference voltage is impressed across program resistor
R1 and, since the voltage is constant, a constant current I
then flows through the output set resistor R2, giving an out-
put voltage of
REF
, between the output and adjustment terminal.
