DESCRIPTIO
The LT®1009 is a precision trimmed 2.5V shunt regulator
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 toler-
ance is achieved by on-chip trimming which not only
minimizes the initial voltage tolerance but also minimizes
the temperature drift.
Even though no adjustments are needed with the LT1009,
a third terminal allows the reference voltage to be adjusted
±5% to calibrate out system errors. In many applications,
the LT1009 can be used as a pin-to-pin replacement of the
LM136 and the external trim network eliminated.
For a lower drift 2.5V reference, see the LT1019 data sheet.
