Overview
The TPR3325-S3TR-S is a fixed-output voltage reference IC from the 3PEAK TPR33 series, providing a nominal output of 2.5 V. It operates within a supply voltage range of 2.1 V to 5.5 V and draws a quiescent current of 180 μA. The device guarantees an initial accuracy of ±0.15% and a temperature coefficient of 30 ppm/°C across the −40°C to +125°C operating range. Output noise is specified at 50 μVpp in the 0.1 Hz to 10 Hz bandwidth. It supports capacitive loads between 0.1 μF and 10 μF and is housed in a SOT23G-3 package.
Feature Summary
- Fixed 2.5 V output with high initial accuracy of ±0.15%
- Extended temperature stability over −40°C to +125°C
- Low quiescent current consumption of 180 μA
- Capacitive load stability from 0.1 μF to 10 μF
Applications

Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and transport media specifications. Ensure the component matches the required SOT23G-3 package type and that the part number corresponds exactly to the 2.5 V fixed output variant within the TPR33 family. Cross-reference the datasheet revision history for any updates to electrical limits or testing conditions before finalizing procurement.
Selection Notes
Select this component when a stable 2.5 V reference is required with tight initial accuracy and low temperature drift. The wide operating temperature range makes it suitable for harsh environments. Verify that the application circuit can accommodate the specified capacitive load range for optimal stability. Consider the low quiescent current for battery-powered designs requiring minimal standby power consumption.
Part Context
The TPR3325-S3TR-S belongs to the TPR33 family of voltage references manufactured by 3PEAK. This series offers multiple fixed output voltages including 1.25 V, 2.048 V, 3 V, 3.3 V, and 4.096 V. All variants share similar performance characteristics such as low noise, high accuracy, and extended temperature operation, making them versatile choices for precision analog circuits.
Replacement Considerations
Direct substitutes within the same family include TPR3320-S3TR (2.048 V), TPR3330-S3TR (3 V), TPR3333-S3TR (3.3 V), and TPR3340-S3TR (4.096 V). These parts share identical pinouts, packages, and general electrical characteristics, differing only in their fixed output voltage levels.
