Overview
The REF5030AIDGKR is a standard-grade precision voltage reference from Texas Instruments, delivering a fixed 3V output. It features an initial accuracy of ±0.1% and a maximum temperature coefficient of 8ppm/°C across the -40°C to 125°C operating range. The device supports input voltages from VOUT + 0.2V up to 18V with a quiescent current of 1.2mA. It provides ±10mA output current capability and includes a low-frequency noise specification of 3µVPP/V (0.1Hz to 10Hz). Packaged in an 8-pin VSSOP.
Feature Summary
- Standard-grade performance with high accuracy and low drift for precision applications
- Capable of sourcing and sinking current with excellent line and load regulation
- Integrated temperature monitoring pin providing a linear voltage response
- Low flicker noise characteristics suitable for sensitive data acquisition systems
Applications
- Precision data acquisition systems
- Industrial process controls
- Medical instrumentation
- Pressure and temperature transmitters
Procurement Notes
Verify the specific grade suffix 'AI' corresponds to the standard-grade specifications (±0.1% accuracy, 8ppm/°C drift) required by the design. Confirm the package suffix 'DGK' matches the 8-VSSOP footprint on the target PCB layout. Ensure the input voltage supply remains within the 18V maximum limit for this grade. Check for any recent product change notifications regarding assembly sites or material composition updates.
Selection Notes
Select this component when a fixed 3V reference with standard-grade precision is sufficient. It offers a balance of low noise and high accuracy without the cost of enhanced grades. Consider the VSSOP package size constraints and thermal resistance characteristics. Verify that the 1.2mA quiescent current fits the system power budget. Ensure the application does not require the higher input voltage support or lower noise of the enhanced grade variants.
Part Context
This part belongs to the REF50xx family of low-noise, very low drift precision voltage references. The REF5030 variant specifically provides a 3V output. The 'A' designation indicates the standard grade, while 'I' denotes high grade and 'E' denotes enhanced grade. The DGK suffix identifies the 8-lead Very Small Outline Package with a 3.00mm width.

FAQ
What is the function of Pin 3 (TEMP)?
Pin 3 provides a temperature-dependent output voltage with a sensitivity of 2.64 mV/°C, allowing for external temperature monitoring.
Does the REF5030AIDGKR support shutdown mode?
No, the standard grade REF50xxAI devices do not have an enable pin. Only the enhanced grade (REF50xxEI) includes an EN pin for shutdown control.
What is the maximum short-circuit current?
The device can withstand a short circuit at the output with a maximum short-circuit current of 25 mA.
