ON NCV1009D 2.5 volt reference Datasheet

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

If the external trim resistor is not used, the “ADJ. PIN” should
be left floating. The 10k trim potentiometer does not effect the

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
