Part Number
The LM236 and LM336 are precision 2.5V regula-
tor diodes. These voltage reference monolithic ICs
operate like 2.5V zener diodes with a low temper-
ature coefficient and a dynamic impedance of
0.2Ω. A third pin enables adjusting the reference
voltage and the temperature coefficient.

APPLICATION HINTS
The LM236, LM336 voltage references are easier
to use than zener diodes. Their low impedance
and wide current range facilitate biasing in any cir-
cuits. Besides, the breakdown voltage or the tem-
perature coefficient can be adjusted so as to opti-
mize the performance of the circuit.
Figure 1 represents a LM336 with a 10kΩ potenti-
ometer to adjust the reverse breakdown voltage
which can be adjusted without altering the temper-
ature coefficient of the circuit. The adjustment
range is generally sufficient to adjust the initial tol-
erance of the circuit and the inaccuracy of the am-
plifier circuit.
To obtain a lower temperature coefficient two di-
odes can be connected in series as indicated in
Figure 2.
When the circuit is adjusted to 2.49V the tempera-
ture coefficient is minimized.
For a correct temperature coefficient, the diodes
should be at the same ambient temperature as the
LM336. The value of R1 is not critical (2-20kΩ).
