Overview
The REF3130AIDBZTG4 is a fixed-output series voltage reference from Texas Instruments, providing a nominal output of 3.0 V. It features an initial accuracy of ±0.2% and a temperature coefficient of 20 ppm/°C. The device operates within an input voltage range of 3.05 V to 5.5 V and draws a supply current of 135 µA. It supports a maximum load current of 10 mA and functions across a junction temperature range of -40°C to +125°C. The component is housed in a surface-mount SOT-23-3 package.
Feature Summary
- Provides a stable 3.0 V reference with high precision and low drift over temperature.
- Operates efficiently with low quiescent current consumption suitable for battery-powered systems.
- Capable of sourcing up to 10 mA of load current while maintaining regulation.
Applications
- Precision analog-to-digital converter (ADC) reference inputs
- Data acquisition system voltage references
- Portable instrumentation power supplies
Procurement Notes
Verify the suffix G4 indicates RoHS compliance and standard manufacturing practices. Confirm the specific tape-and-reel packaging quantity matches the procurement requirement. Ensure the ordering part number aligns exactly with the required output voltage and tolerance specifications before finalizing orders.
Selection Notes
Select this component when a fixed 3.0 V reference is required with tight initial accuracy and moderate load drive capability. It is suitable for applications needing low noise and stability over a wide industrial temperature range. Consider the SOT-23-3 footprint constraints and thermal dissipation requirements during PCB layout.
Part Context
This part belongs to the REF31xx family of low-power, low-noise voltage references. It shares architectural similarities with other members like the REF3133 but differs in fixed output voltage. The family is designed for space-constrained applications requiring high precision in a compact surface-mount package.
Replacement Considerations
Direct pin-compatible substitutes within the same family include REF3130AIDBZR. Verify that alternative sources maintain identical electrical characteristics, particularly the 20 ppm/°C temperature coefficient and ±0.2% initial accuracy, to ensure circuit compatibility.
