Description

AI
The LT1009 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 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.ApplicationsReference for 5V Systems8-Bit A/D and D/A ReferenceDigital VoltmetersCurrent Loop Measurement and Control SystemsPower Supply Monitor
