STMicroelectronics LM336B
The LM336 with Pot for Adjustment of Breakdown Voltage cient of the circuit. The adjustment range is generally sufficient to adjust the initial tolerance of the circuit and the inaccuracy of the amplifier circuit. When the circuit is adjusted to 2.49V the temperature coefficient is minimized.DESCRIPTION
The LM236 and LM336 are precision 2.5V regulator diodes. These voltage reference monolithic ICs operate like 2.5V zener diodes with a low temperature coefficient and a dynamic impedance of 0.2Ω. A third pin enables adjusting the reference voltage and the temperature coefficient.
