The RT9183 series are high performance linear voltage regulators that provide ultra low-dropout voltage, high output current with low ground current. It operates from an input of 2.3V to 5.5V and provides output current up to 1.5A thus is suitable to drive digital circuits requiring low voltage at high currents.<br />The RT9183 has superior regulation over variations in line and load. Also it provides fast respond to step changes in load. Other features include over-current and over-temperature protection. The adjustable version has enable pin to reduce power consumption in shutdown mode.<br />The devices are available in fixed output voltages of 1.2V to 3.3V with 0.1V per step and as an adjustable device with a 0.8V reference voltage. The RT9183 regulators are available in 3-lead SOT-223 and TO-263 packages (fixed output only for the 3-lead option). Also available are 5-lead TO-263, TO-252 and fused SOP-8 packages with two external resistors to set the output voltage ranges from 0.8V to 4.5V.</p>
