The LT

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.
