LT1009 Series
2.5V Reference
FEATURES
DESCRIPTION
The LT®1009 is a precision trimmed 2.5V shunt regula-
tor diode featuring a maximum initial tolerance of only
5mV. The low dynamic impedance and wide operating
current range enhances its versatility. The 0.2% reference
tolerance is achieved by on-chip trimming which not only
minimizes the initial voltage tolerance but also minimizes
the temperature drift.

No Adjustments Needed for Minimum Temperature
Coefficient
Even though no adjustments are needed with the LT1009,
athirdterminalallowsthereferencevoltagetobeadjusted
5% to calibrate out system errors. ꢀn many applications,
the LT1009 can be used as a pin-to-pin replacement of the
LM136 and the external trim network eliminated.
