RT9183-12PG
® RT9183 Ultra Low Dropout 1.5A Linear Regulator General Description 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. 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 overtemperature protection. The adjustable version has enable pin to reduce power consumption in shutdown mode. 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 5lead TO-263, TO-252 and fused SOP-8 packages with two Features 330mV Dropout @ 1.5A 380μA Low Ground Pin Current μ Excellent Line and Load Regulation 0.1μA Quiescent Current in Shutdown Mode μ Guaranteed 1.5A Output Current Fixed Output Voltages : 1.2V to 3.3V Adjustable Output Voltage from 0.8V to 4.5V Over-Temperature/Over-Current Protection RoHS Compliant and 100% Lead (Pb)-Free Ordering Information RT9183 - external resistors to set the output voltage ranges from 0.8V to 4.5V.
