Product Overview: LT1118CST-2.85#PBF

The LT1118CST-2.85#PBF is a high-performance, low dropout linear regulator from Linear Technology, designed to provide a fixed output voltage of 2.85V with an input voltage range from 3.8V to 20V. This regulator is capable of delivering up to 800mA of continuous output current with a typical dropout voltage of just 0.15V at full load, making it an excellent choice for tight voltage regulation in battery-powered systems.

The device features a low ground current, which remains nearly constant regardless of the load, thus improving battery life in portable applications. Additionally, the LT1118 has a fast transient response, which is essential for applications requiring a stable voltage supply despite rapid changes in load, such as digital circuits and microprocessor-based systems.

The LT1118CST-2.85#PBF comes in a thermally efficient surface-mount SOT-223 package, which is suitable for compact designs where space is at a premium. With its integrated overcurrent and overtemperature protection, the regulator ensures reliable operation and longevity of the end application. The LT1118 also features a shutdown capability that allows the output to be turned off, thus reducing the quiescent current to nearly zero and further extending battery life when the system is in standby mode.
