TPR3520-S3TR

Overview

The TPR3520-S3TR is a shunt voltage reference from the 3PEAK TPR35 family, providing a fixed output of 2.048 V in an SOT23G-3 package. It operates within a supply voltage range of 2.1 V to 5.5 V and supports an output current up to 20 mA. The device guarantees high initial accuracy with a maximum tolerance of ±0.2% and features low temperature drift of 30 ppm/°C over the industrial range (-40°C to 85°C) and 50 ppm/°C over the extended range (-40°C to 125°C). Quiescent current is typically 210 μA, and it maintains stability with capacitive loads between 0.1 μF and 10 μF.

Feature Summary

• High initial accuracy with a maximum tolerance of ±0.2%
• Low temperature coefficient ensuring stable performance across wide operating ranges
• Capacitive load stability supporting values from 0.1 μF to 10 μF

Applications

• Power systems
• Instrumentation
• Industrial equipment

Procurement Notes

Verify the specific part number TPR3520-S3TR against official 3PEAK documentation to confirm the 2.048 V output voltage and SOT23G-3 package configuration. Ensure that the required operating temperature range aligns with the specified -40°C to 125°C limits for your application environment. Confirm compliance with RoHS standards and halogen-free requirements as defined by the manufacturer's green product specifications.

Selection Notes

Select this component when a precise 2.048 V reference is required with tight initial accuracy and low thermal drift. It is suitable for designs needing stable performance under varying load conditions and temperatures. Consider the quiescent current and dropout voltage characteristics relative to the system power budget and input voltage constraints.

Part Context

This component belongs to the TPR35 series of voltage references manufactured by 3PEAK (思瑞浦). The series offers various fixed output voltages including 1.25 V, 2.048 V, 2.5 V, 3 V, 3.3 V, and 4.096 V. All variants share similar electrical characteristics regarding accuracy, noise, and temperature stability, packaged in SOT23G-3 for surface-mount applications.

Replacement Considerations

Other members of the TPR35 family such as TPR3525-S3TR or TPR3530-S3TR offer different fixed output voltages but share identical packages and general electrical characteristics. Verify that the alternative voltage level meets the circuit design requirements before substitution.
