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.

• Extended Operating Temperature Range for Use in Automotive
• 0.2% Initial Tolerance Max.
• Directly Interchangeable with LT1009 and LM136 for Improved
