Features Low temperature coefficient Wide operating current of 400 µA to 10 mA 0.2 dynamic impedance ±1% initial tolerance available Guaranteed temperature stability Easily trimmed for minimum temperature drift Fast turn-on Description The LM136-2.5/LM236-2.5 and LM336-2.5 integrated circuits are precision 2.5V shunt regulator diodes. These monolithic IC voltage references operate as a low-temperature-coefficient 2.5V zener with 0.2 dynamic impedance. A third terminal on the LM136-2.5 allows the reference voltage and temperature coefficient to be trimmed easily. The LM136-2.5 series is useful as a precision 2.5V low voltage reference for digital voltmeters, power supplies or op amp circuitry. The 2.5V make it convenient to obtain a stable reference from 5V logic supplies. Further, since the LM136-2.5 operates as a shunt regulator, it can be used as either a positive or negative voltage reference. The LM136-2.5 is rated for operation over -55°C to +125°C while the LM236-2.5 is rated over a -25°C to +85°C temperature range. The LM336-2.5 is rated for operation over a 0°C to +70°C temperature range. See the connection diagrams for available packages.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
