LT1009 - 2.5V Reference

1 LT1009 Series11009ff TYPICAL APPLICATION FEATURES APPLICATIONS ReferenceThe LT 1009 is a precision trimmed 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 Reference tolerance is achieved by on-chip trimming which not only minimizes the initial voltage tolerance but also minimizes the temperature 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 a lower drift Reference , see the LT1019 data Referencen Reference for 5V Systemsn 8-Bit A/D and D/A Referencen Digital Voltmetersn Current Loop Measurement and Control Systemsn Power Supply MonitorL, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
