ZHCSHO3L January 1989 – February 2018 LM285-2.5 , LM385-2.5 , LM385B-2.5
PRODUCTION DATA.
The LMx85-2.5 and LM385B-2.5 devices have a single functional mode. These devices can be used as 2.5-V fixed voltage references. The reference voltage cannot be adjusted for these devices.
For a proper Reverse Voltage to be developed, current must be sourced into the cathode of LM285. The minimum current needed for proper regulation is denoted in Electrical Characteristics as IZ(MIN).
