DESCRIPTION
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 tolerance is achieved by on-chip trimming which not only minimizes the initial voltage tolerance but also minimizes the temperature drift.

FEATURES
■ 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

APPLICATIONS
■ Reference for 5V Systems
■ 8-Bit A/D and D/A Reference
■ Digital Voltmeters
■ Current Loop Measurement and Control Systems
■ Power Supply Monitor
