Infineon Technologies AG Voltage Regulators - Linear IRU1206-18CD

The IRU1206-18CD is a linear voltage regulator designed to provide a fixed output voltage of 1.8V with a maximum output current of 1A. It features a low dropout voltage of 500mV at 1A, making it suitable for applications where the input voltage is close to the output voltage. The device operates with a quiescent current of 1µA in shutdown mode, enhancing its efficiency in low-power applications. This regulator is particularly useful in scenarios where a single input supply is available, such as powering logic ICs from a 3.3V source to achieve a 1.8V output. It includes features like current limit protection, thermal shutdown, and an error flag signal to indicate when the output is out of regulation. The IRU1206-18CD is available in a compact 2-pin TO-252 package, making it suitable for space-constrained designs. Engineers may consider this product for applications in computer motherboards, add-on cards, and as a post regulator in switch mode power supplies due to its fast transient response and low dropout characteristics.
