NCV1009_06 Datasheet, PDF (1/6 Pages) ON Semiconductor – 2.5 Volt Reference

NCV1009
2.5 Volt Reference
The NCV1009 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 on−chip 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 NCV1009Z
can be used as a pin−to−pin replacement of the LT1009CZ and the
LM136Z−2.5 with the external trim network eliminated.
Features
• 0.2% Initial Tolerance Max.
• Guaranteed Temperature Stability
• Maximum 0.6 W 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
• Extended Operating Temperature Range for Use in Automotive
Applications
• NCV Prefix, for Automotive and Other Applications Requiring Site
and Change Control
• Pb−Free Packages are Available

*±5.0% Trim Range
If the external trim resistor is not used, the “ADJ. PIN” should
be left floating. The 10k trim potentiometer does not effect the
temperature coefficient of the device.
