LT1009 Series
2.5V Reference
FEATURES DESCRIPTION n 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. 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

Current Loop Measurement and Control Systems
Power Supply Monitor 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, …
