NCV1009Z

Overview

The NCV1009Z is a precision trimmed 2.5 V shunt regulator diode designed for automotive and industrial applications. It features a low dynamic impedance and a wide operating current range to enhance versatility. The device achieves tight reference tolerance through on-chip trimming, minimizing voltage tolerance and temperature drift. A third terminal allows the reference voltage to be adjusted by +/-5.0% to calibrate out system errors. It offers an extended operating temperature range suitable for automotive environments.

Feature Summary

• Precision on-chip trimming minimizes voltage tolerance and temperature drift
• Third terminal enables +/-5.0% reference voltage adjustment for system error calibration
• Low dynamic impedance supports versatile operation across a wide current range

Applications

• Automotive systems requiring extended temperature range performance
• Applications needing precise 2.5 V reference calibration
• Circuits replacing LT1009 or LM136 with eliminated external trim networks

Procurement Notes

Verify the specific suffix Z indicates the TO-92-3 package configuration when sourcing. Confirm that the NCV prefix denotes automotive qualification requirements relative to standard commercial variants. Ensure the ordering part number matches the required lead frame finish and compliance standards specified in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.5 V reference with adjustable calibration capability is required. The integrated trim terminal simplifies design by removing the need for external resistor networks used in comparable legacy devices. Consider the TO-92-3 package constraints for board space and thermal dissipation needs in compact automotive assemblies.
