LM136-2.5-N, LM236-2.5-N, LM336-2.5-NV Reference Diode

Check for Samples: LM136-2.5-N

FEATURES

The LM136-2.5-N series is useful as a precision 2.5V

• 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

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.

APPLICATION HINTS The LM136 series voltage references are much easier to use than ordinary zener diodes. Their low impedance and wide operating current range simplify biasing in almost any circuit. Further, either the breakdown voltage or the temperature coefficient can be adjusted to optimize circuit performance.
