Overview
The REF3025TB-GT3 is a CMOS voltage reference from the REF30xx family, manufactured by onsemi. It provides a nominal output voltage of 2.5 V with an initial accuracy of ±0.2%. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a maximum load current of 10 mA for both sourcing and sinking. It features a maximum temperature drift of 50 ppm/°C over the specified operating range of -40°C to +85°C. The component is housed in a space-saving SOT-23 (CASE 527AG) package.
Feature Summary
- High precision with ±0.2% initial accuracy
- Low quiescent current consumption of 30 µA maximum
- Capable of sourcing or sinking up to 10 mA load current
- Maximum temperature drift of 50 ppm/°C across the operating range
Applications
- Battery powered systems
- A/D and D/A converters
- Precision regulator systems
- Portable medical equipment
Procurement Notes
Verify the specific suffix TB indicates the SOT-23 package configuration and GT3 denotes tape and reel shipping. Confirm RoHS compliance and lead-free status as stated in the datasheet. Ensure the ordering part number matches the required 2.5 V output specification. Check for any recent product change notices regarding packaging or manufacturing location updates.
Selection Notes
Select this component when a stable 2.5 V reference is required in space-constrained designs using the SOT-23 footprint. It is suitable for applications demanding low power consumption and high accuracy without external compensation capacitors in most scenarios. Consider the 10 mA drive capability if driving moderate loads directly.
Part Context
This part belongs to the REF30xx series of high-precision, low-drift CMOS voltage references. The family includes variants with outputs ranging from 1.25 V to 4.096 V. All members share similar electrical characteristics, including low noise and high PSRR, while differing primarily in their fixed output voltage levels and marking codes.
Replacement Considerations
Other members of the REF30xx family such as REF3012TB-GT3, REF3020TB-GT3, REF3030TB-GT3, REF3033TB-GT3, and REF3040TB-GT3 are pin-compatible alternatives offering different voltage outputs.
