■ FAST TURN-ON

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 tempe r­ature coefficient and a dynamic impedance of

0.2Ω. A third pin enables adjusting the reference
voltage and the temperature coefficient.
