LM336-2.5 - Voltage Reference Diode

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 series is useful as precision 2.5-V low-voltage references (VZ) for digital voltmeters, power supplies, or operational-amplifier circuitry. The 2.5-V voltage reference makes it convenient to obtain a stable reference from 5-V logic supplies.

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
(This was used by me in the manufacture of Indicators and Controllers and was used in place of ICL8609  as that was not in supply)
