FEATURES
The LM136-2.5-N series is useful as a precision 2.5V
2
• Low Temperature Coefficient
low voltage reference for digital voltmeters, power
• Wide Operating Current of 400 μA to 10 mA
supplies or op amp circuitry. The 2.5V make it
• 0.2Ω Dynamic Impedance
convenient to obtain a stable reference from 5V logic
supplies. Further, since the LM136-2.5-N operates as
• ±1% Initial Tolerance Available
a shunt regulator, it can be used as either a positive
• Specified Temperature Stability
or negative voltage reference.
• Easily Trimmed for Minimum Temperature Drift
The LM136-2.5-N is rated for operation over −55°C to
• Fast Turn-On
+125°C while the LM236-2.5-N is rated over a −25°C
to +85°C temperature range.
DESCRIPTION
The LM336-2.5-N is rated for operation over a 0°C to
The LM136-2.5-N/LM236-2.5-N and LM336-2.5-N
+70°C temperature range. See the connection

diodes. These monolithic IC voltage references
operate as a low-temperature-coefficient 2.5V zener
with 0.2Ω dynamic impedance. A third terminal on the
LM136-2.5-N allows the reference voltage and
temperature coefficient to be trimmed easily.
