L79L06ABUTR

Overview

The STMicroelectronics L79L06ABUTR is a three-terminal negative voltage regulator from the L79L00 series, providing a fixed -6 V output. It delivers up to 100 mA of output current and operates within an extended temperature range of -40 °C to +125 °C. The device incorporates internal thermal overload protection and short-circuit protection, ensuring robust performance without requiring external components for basic regulation.

Feature Summary

• Integrated thermal overload and short-circuit protection mechanisms
• Fixed -6 V output with ±5% accuracy selection
• Extended industrial operating temperature range

Applications

• Local or on-card negative voltage regulation
• Replacement for Zener diode/resistor combinations
• Noise elimination in single-point regulation systems

Procurement Notes

Verify that the ordering suffix 'UTR' corresponds to the specified tape and reel packaging configuration as documented in official STMicroelectronics catalogs. Confirm the 'AB' designation aligns with the required -40 °C to +125 °C operating temperature range and ±5% output voltage tolerance specifications before finalizing procurement.

Selection Notes

Select this component when a stable negative rail is required for low-current applications under 100 mA. The extended temperature rating makes it suitable for industrial environments where standard commercial grade parts may fail. Ensure input voltage remains within absolute maximum ratings to maintain regulation integrity.

Part Context

This part belongs to the L79L00 series of three-terminal negative regulators. The series offers various fixed output voltages including -5, -8, -9, -12, and -15 V. The L79L06 variant specifically targets -6 V requirements, sharing common package options like SO-8, SOT-89, and TO-92 across the family.

Replacement Considerations

Compatible replacements include other L79L06 variants such as L79L06AC or L79L06C, provided the operating temperature range and voltage tolerance meet system requirements.
