Overview
The L7809CP is a fixed positive linear voltage regulator from the STMicroelectronics L78xx series, designed for general-purpose applications. It provides a nominal output voltage of 9 V with a maximum output current capability of 1.5 A. The device operates within an input voltage range of 10.5 V to 35 V and features internal protections against overload current, short circuit conditions, and thermal overload. It is housed in a TO-220 package.
Feature Summary
- Internal overload current protection
- Short circuit protection
- Thermal overload protection
Applications
- General-purpose power supplies
- Local regulation for on-card distribution
- Embedded systems requiring stable DC voltage
Procurement Notes
Verify that the specific part number matches the required package type (TO-220) and output tolerance. Confirm RoHS compliance status if restricted materials are prohibited in your assembly process. Ensure the supplier source is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component when a fixed 9 V output is required at currents up to 1.5 A. Consider the thermal dissipation requirements associated with the TO-220 package under high load or high input-output differential conditions. Verify that the input voltage remains within the specified operational limits to ensure stability.
Part Context
This component belongs to the L78xx family of three-terminal positive linear regulators. These devices are widely used for their simplicity and reliability in basic voltage regulation tasks. The L7809 variant specifically targets applications needing a stable 9 V rail derived from higher voltage sources.
