LT1009 Series 2.5V Reference Features s s s s s DESCRIPTIO s Maximum Initial Tolerance: 0.2% Guaranteed Temperature Stability Maximum 0.6Ω Dynamic Impedance Wide Operating Current Range Directly Interchangeable with LM136 for Improved Performance No Adjustments Needed for Minimum Temperature Coefficient The LT®1009 is a precision trimmed 2.5V shunt regulator diode featuring a maximum initial tolerance of only ± 5m V. 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. 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. , LTC and LT are registered trademarks of Linear Technology Corporation.
