L7906CV

Overview

The L7906CV is a fixed negative linear voltage regulator from the STMicroelectronics L79 series, designed for general-purpose applications. It provides a fixed output of -6 V with a maximum load current capability of 1.5 A. The device accepts an input voltage range from -8 V to -35 V and operates within a junction temperature range of 0 °C to +150 °C. Key electrical specifications include a typical quiescent current of 3 mA, line regulation of 120 mV, and load regulation of 120 mV. It features built-in thermal overload protection and short-circuit current limiting. The component is housed in a TO-220-3 through-hole package.

Feature Summary

• Provides a stable fixed negative DC output voltage suitable for power supply circuits requiring negative rails.
• Incorporates internal thermal overload protection and short-circuit current limiting to ensure device safety under fault conditions.
• Utilizes a robust TO-220-3 through-hole package that facilitates efficient heat dissipation for high-current operation.

Applications

• Negative rail generation in dual-supply electronic systems
• Power management modules for analog signal processing circuits
• Industrial control equipment requiring stable negative voltage references

Procurement Notes

Verify the specific manufacturer part number against official STMicroelectronics documentation to confirm the -6 V output specification. Ensure the procurement channel provides valid RoHS compliance data and authentic component sourcing. Cross-reference the TO-220-3 package marking to distinguish it from other L79xx variants with different voltage outputs.

Selection Notes

Select this component when a fixed negative voltage is required for linear regulation applications. The 1.5 A current rating and TO-220-3 package make it suitable for moderate power dissipation scenarios. Consider the minimum input voltage requirement relative to the desired output to maintain adequate dropout voltage margin during operation.

Part Context

This component belongs to the L79xx family of negative linear regulators manufactured by STMicroelectronics. The family offers various fixed output voltages to support diverse power supply design requirements. These regulators are widely used in industrial and commercial electronics where reliable negative voltage generation is necessary.

Replacement Considerations

Compatible substitutes include the LM7906 and MC7906. Verify pinout compatibility and thermal performance characteristics before substitution to ensure circuit integrity.
