Overview
The REF3130AIDBZR is a series voltage reference IC manufactured by Texas Instruments, housed in a compact SOT-23-3 surface-mount package. It provides a fixed output voltage of 3V with an initial accuracy tolerance of ±0.2%. The device operates within an input voltage range of 3.05V to 5.5V and draws a supply current of 135µA. It supports a maximum output current of 10mA and features a temperature coefficient of 20ppm/°C. Noise performance is specified at 39µVp-p (0.1Hz to 10Hz) and 57µVrms (10Hz to 10kHz). The component functions reliably across an operating temperature range of -40°C to +125°C.
Feature Summary
- Delivers high precision with a fixed 3V output and tight ±0.2% initial accuracy tolerance for sensitive analog circuits.
- Optimized for low power consumption with a quiescent current of 135µA, suitable for battery-operated systems.
- Provides stable reference performance over a wide industrial temperature range from -40°C to +125°C.
Applications
- Portable instrumentation requiring precise voltage references
- Battery-powered measurement devices
- Data acquisition systems
Procurement Notes
Verify the complete part number including suffixes such as 'R' for reel packaging when ordering. Confirm that the specific revision matches design requirements. Check RoHS compliance status if environmental regulations apply to the assembly process. Ensure the SOT-23-3 footprint aligns with the PCB layout specifications before finalizing procurement.
Selection Notes
Select this component when a fixed 3V reference with high accuracy is required in a small form factor. Compare noise specifications against application needs, noting the 39µVp-p low-frequency noise. Consider the 10mA load capability for driving downstream circuitry without external buffering. Evaluate the 20ppm/°C temperature drift against thermal environment constraints.
Part Context
This device belongs to the REF31xx series of low-current, low-dropout voltage references from Texas Instruments. The series offers various fixed output voltages while maintaining consistent performance characteristics. The REF3130 variant specifically targets applications needing a 3V rail derived from higher supply voltages up to 5.5V.
Replacement Considerations
The REF3130AIDBZRG4 is a verified lead-free replacement variant within the same family. Verify pin compatibility and electrical parameter equivalence before substitution.
