Overview
The NCV1009DG is a precision trimmed 2.5 V shunt regulator diode manufactured by onsemi in an 8-SOIC package. It features a maximum initial tolerance of ±0.32% and a temperature coefficient of 15 ppm/°C. The device operates within a temperature range of -40°C to 125°C and supports a cathode current up to 10 mA with a supply current of 400 µA. An external trim terminal allows for voltage adjustment of ±5.0% to calibrate system errors.
Feature Summary
- Precision trimming minimizes voltage tolerance and temperature drift
- Third terminal enables reference voltage adjustment for system error calibration
- Low dynamic impedance enhances versatility across wide operating current ranges
Applications
- Automotive electronic systems requiring extended temperature operation
- High-accuracy analog-to-digital converter references
- Precision measurement instrumentation
Procurement Notes
Verify the specific suffix DG indicates the 8-SOIC surface-mount package configuration. Confirm automotive qualification status through official datasheets, as NCV prefixes typically denote automotive-grade components. Ensure compatibility with existing PCB footprints for SOIC-8 narrow body packages during procurement planning.
Selection Notes
Select this component when a stable 2.5 V reference is required in space-constrained designs. The 8-SOIC package offers higher pin density compared to TO-92 alternatives. Consider the adjustable trim feature if system-level calibration is necessary to eliminate offset errors without additional external circuitry complexity.
Part Context
This part belongs to the NCV1009 series of 2.5 Volt References. It serves as a direct replacement for legacy parts like the LT1009 and LM136Z-2.5, eliminating the need for external trim networks in many applications. The series provides both through-hole (TO-92) and surface-mount options to suit diverse manufacturing requirements.
Replacement Considerations
Directly interchangeable with LT1009 and LM136Z-2.5. Verify pinout compatibility when substituting these legacy devices. No external trim network is required for standard operation.
