L7906

Overview

The L7906 is a negative fixed linear voltage regulator IC manufactured by Lumimax Optoelectronic Technology. It provides a stable -6V output with a maximum load current of 1.5A. The device features internal protection mechanisms including over-current, over-temperature, and short-circuit safety. It operates within a junction temperature range of -25°C to 125°C and exhibits a quiescent current of 5mA with a power supply rejection ratio of 60dB at 120Hz.

Feature Summary

• Fixed negative voltage regulation
• Integrated thermal and current protection
• High ripple rejection capability

Applications

• General-purpose power supply circuits requiring negative rails
• Industrial control systems
• Consumer electronics power management

Procurement Notes

Verify the specific manufacturer origin as Lumimax Optoelectronic Technology may act as a distributor for components originally produced by other semiconductor manufacturers such as STMicroelectronics. Confirm package type TO-220 availability and ensure RoHS compliance status matches project requirements before finalizing procurement orders.

Selection Notes

Select this component when a reliable -6V DC source is needed for analog or digital circuits. Ensure the input voltage remains sufficiently higher than the output to maintain regulation and account for power dissipation limits in the TO-220 package under expected load conditions.

Part Context

This part belongs to the family of negative linear voltage regulators. It serves as a complement to positive regulators like the 78xx series, enabling dual-polarity power supplies essential for operational amplifiers and mixed-signal applications in industrial and commercial electronic designs.

Replacement Considerations

Compatible substitutes include the STMicroelectronics L7906CV and generic equivalents labeled as LM7906 or UA7906. Verify pinout compatibility and thermal performance characteristics when swapping between different manufacturer sources.
