TS3330ACR

Overview

The TS3330ACR is a micropower high-precision series voltage reference manufactured by STMicroelectronics. It provides a fixed output voltage of 3V with an initial accuracy of ±0.15%. The device operates within an input voltage range of 1.8V to 5.5V and supports a maximum shunt current of 5mA. It features a low operating supply current of 3.9µA and a temperature coefficient of 30ppm/°C. The component functions reliably across an extended temperature range from -40°C to +125°C. It is housed in a compact SOT-323-3 surface-mount package, designed for space-constrained applications requiring stable voltage regulation.

Feature Summary

• Delivers stable and precise fixed output voltage suitable for sensitive analog circuits
• Optimized for low power consumption with micropower operating current characteristics
• Maintains high precision over a wide industrial temperature range

Applications

• Portable battery-powered instrumentation systems
• Handheld measurement devices requiring stable reference sources

Procurement Notes

Verify the specific suffix 'CR' indicates the SOT-323-3 package and tape-and-reel shipping configuration. Confirm that the order quantity aligns with manufacturer reel requirements if full reels are necessary. Ensure compatibility with the target PCB footprint for the three-terminal surface-mount design. Check for any specific material declaration or RoHS compliance documentation required for your manufacturing process.

Selection Notes

Select this component when a fixed 3V reference is required with tight initial accuracy tolerances. Consider the SOT-323-3 package size constraints against available board space. Evaluate the 30ppm/°C temperature coefficient against environmental thermal variations. Compare the 3.9µA quiescent current against system power budget limitations for battery-operated designs.

Part Context

This part belongs to the TS33 family of low-power series voltage references from STMicroelectronics. The family offers various fixed output voltages and packages while maintaining consistent precision standards. The TS3330ACR specifically targets applications demanding a 3V reference in a minimal footprint. It complements other PMIC solutions where dedicated, stable voltage rails are critical for signal integrity.

Replacement Considerations

Check for direct pin-compatible alternatives within the same TS33 family offering different voltage outputs. Verify if other manufacturers provide equivalent 3V references with similar accuracy and package dimensions. Ensure thermal performance and noise specifications meet the original design requirements before substitution.
