REG103UA-A General Description

The REG103UA-A is equipped with robust protection features to safeguard both the regulator and the connected load. Internal circuitry enforces a current limit to prevent damage to the load, while thermal protection mechanisms prevent overheating of the regulator chip. Available in multiple package options, including SO-8, DDPAK, and SOT223-5, the REG103UA-A offers flexibility in design and application. Tested rigorously across a wide temperature range, from -40°C to +85°C, this regulator ensures reliable performance in diverse operating conditions
