PRODUCT DESCRIPTION

The CLM285 / 385 - 2.5 are 2 terminal band-gap voltage
regulator diodes. Operating over a 20µA to 20mA current range.
The de vices p rovi de good tem perat ure s tabilit y and exceptionally
low dynamic i mpedance. Desi gned for appl ications i n portable
meters, regulators or general purpose cir cuitry.
