The LDI1117-1.8U is a low dropout (LDO) linear voltage regulator designed to provide a fixed output voltage of 1.8V. It operates with an input voltage range of 3.2V to 10V and can deliver output currents up to 1.35A. The dropout voltage is specified at 1.15V when supplying 1A, making it suitable for applications where minimal voltage drop is critical. This regulator features integrated current limiting and thermal overload protection, ensuring reliable operation under varying load conditions. It has a line regulation of 0.2% and a load regulation of 0.4%, indicating stable output voltage across different input voltages and load currents. The quiescent current is low, typically around 10mA, which contributes to overall efficiency. The LDI1117-1.8U is compliant with RoHS standards and is available in a SOT-89 package, making it suitable for compact designs. Typical applications include high-efficiency linear regulation, active SCSI termination, and post-regulation for DC-DC converters.
