Add the CP7912V170FWF to your BOM (Bill of Materials) today. Your negative voltage rails will thank you. Disclaimer: Always refer to the latest manufacturer datasheet for absolute maximum ratings and thermal calculations. This article is for informational purposes based on typical industry data.
At maximum load (1.7A) with a high input voltage (e.g., -24V to -12V drop), you are dissipating ~20W of heat. The FWF package is designed for a vertical fin heatsink. Rule of thumb: If the ambient temperature exceeds 50°C, forced airflow or a larger heatsink is mandatory. cp7912v170fwf best
Treat the negative regulator differently than a positive one. The tab is connected to the input (not ground). Use a star ground topology to prevent load currents from modulating the reference ground.
