Overview
The L7906CD2T-TR is a fixed negative linear voltage regulator from the L79xx series by STMicroelectronics. It provides a stable -6V output with a maximum continuous current of 1.5A. The device features internal thermal overload and short-circuit protection, ensuring robust operation in surface-mount applications. It operates within an input voltage range up to -40V and supports junction temperatures up to 150°C. Packaged in a D2PAK (TO-263) housing, it offers a compact solution for power management systems requiring reliable negative voltage regulation.
Feature Summary
- Fixed negative output voltage regulation
- Internal thermal overload and short-circuit protection
- Surface-mount D2PAK package design
Applications
- Negative power supply rails in electronic circuits
- General-purpose linear voltage regulation
- Power management modules
Procurement Notes
Verify the exact part number suffix against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Confirm that the D2PAK variant matches your PCB footprint requirements. Check for lifecycle status updates as older revisions may be obsolete. Ensure compatibility with your system's thermal dissipation needs given the 1.5A current rating.
Selection Notes
Select this component when a fixed -6V negative rail is required with moderate current capacity. The D2PAK package suits applications needing better thermal performance than smaller SOT packages while maintaining a surface-mount profile. Consider the maximum input voltage limit and thermal resistance characteristics during circuit design to ensure safe operating area compliance under load.
Part Context
This component belongs to the L79xx series of three-terminal negative regulators. It shares functional similarities with other members like L7905 or L7912 but differs in output voltage. The series is known for simplicity and reliability in standard linear regulation tasks. The D2PAK variant specifically addresses the need for improved heat dissipation compared to through-hole alternatives.
