Product Summary

The RT9183 is a high performance linear voltage regulator that provides 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. The device is 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 applications of the RT9183 are Battery-Powered Equipment, Mother Board/Graphic Card, Peripheral Cards, PCMCIA Card.
