CS1009/D
CS1009
2.5 Volt Reference
The CS1009 is a precision trimmed 2.5 V
5.0 mV shunt regulator
diode. The low dynamic impedance and wide operating current range
enhances its versatility. The tight reference tolerance is achieved by
onchip trimming which minimizes voltage tolerance and temperature
drift.
A third terminal allows the reference voltage to be adjusted
5.0%
to calibrate out system errors. In many applications, the CS1009GZ
can be used as a pintopin replacement of the LT1009CZ and the
LM136Z2.5 with the external trim network eliminated.
Features
0.2% Initial Tolerance Max.
Guaranteed Temperature Stability
Maximum 0.6
Dynamic Impedance
Wide Operating Current Range
Directly Interchangeable with LT1009 and LM136 for Improved
Performance
No Adjustments Needed for Minimum Temperature Coefficient
Meets Mil Std 883C ESD Requirements
