The RT9183-33GG is a 1.5A ultra low dropout Linear Regulator provides ultra low-dropout voltage, high output current with low ground current. It operates from an input of 2.3 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 regulator 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.
