Overview
The REF5030IDGKT is a high-grade precision series voltage reference from Texas Instruments, delivering a fixed 3V output. It features an initial accuracy of ±0.05% and a maximum temperature coefficient of 3ppm/°C across the -40°C to +125°C range. The device supports input voltages up to 18V and provides a maximum output current of ±10mA. Packaged in an 8-pin VSSOP, it operates with a quiescent current of approximately 1.2mA.
Feature Summary
- High-precision bandgap architecture ensuring excellent initial accuracy and low temperature drift
- Capable of both sourcing and sinking current for flexible load driving
- Integrated trim/noise reduction pin for optimizing performance
- Temperature monitoring pin providing a linear voltage response
Applications
- Precision data acquisition systems
- Semiconductor test equipment
- Industrial process controls
- Medical instrumentation
- Pressure and temperature transmitters
Procurement Notes
Verify the specific suffix 'DGKT' corresponds to the VSSOP-8 package and tape-and-reel shipping format. Confirm that the 'I' grade designation matches the required 3ppm/°C drift specification. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the datasheet thermal information section.
Selection Notes
Select this component when a fixed 3V reference with high accuracy is required. The VSSOP-8 package offers a compact footprint suitable for space-constrained designs. Consider the 18V maximum input voltage limit and the need for external capacitors for stability if operating near the limits of the recommended conditions.
Part Context
This part belongs to the REF50xx family of low-noise, very low drift precision voltage references. It represents the high-grade variant within the series, distinguished by its tighter drift specifications compared to standard grades. The family includes enhanced and standard options, with the REF5030 specifically providing a 3V output level.

FAQ
What is the function of Pin 5 on the REF5030IDGKT?
Pin 5 serves as the TRIM/NR pin, which allows for output adjustment or noise reduction capabilities.
Does the REF5030IDGKT support shutdown mode?
No, the REF5030IDGKT (High Grade) does not include an enable pin; only the Enhanced Grade (REF50xxEI) variants feature an EN pin for shutdown control.
