TLV803EA29RDBZR

Supervisors Overview

The TLV803EA29RDBZR is a low-power voltage supervisor from the TLV803E series, manufactured by Texas Instruments. It operates within a supply voltage range of 1.7 V to 6 V and features a fixed threshold voltage of 2.93 V with 0.5% accuracy. The device provides an active-low, open-drain output and includes a reset delay time of 200 ms. It consumes only 400 nA of static current and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount case, it lacks manual reset, watchdog timer, or backup battery switching capabilities.

Supervisors Feature Summary

• Ultra-low quiescent current consumption for extended battery life
• High precision voltage monitoring with tight threshold accuracy
• Compact three-terminal surface-mount packaging for space-constrained designs

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-operated systems needing reliable voltage supervision
• Embedded controllers requiring stable reset signals during power transitions

Supervisors Procurement Notes

Verify the specific suffix 'EA' against official Texas Instruments documentation to confirm the exact threshold voltage and package variant. Ensure compatibility with your system's voltage levels and thermal requirements. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest datasheet revision notes before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a precise 2.93 V threshold is required for single-input monitoring. Consider the 200 ms reset delay for applications tolerant of longer startup times. Evaluate the SOT-23-3 footprint against available board space. Compare static current specifications against other supervisors if ultra-low power is critical. Verify that the open-drain output interface matches the receiving logic circuitry requirements.
