® RT9018A/B Maximum 3A, Ultra Low Dropout Regulator General Description Features The RT9018A/B is a high performance positive voltage regulator designed for use in applications requiring very low Input voltage and very low dropout voltage at up to 3A(Peak). It operates with a VIN as low as 1.4V and VDD voltage 3V with output voltage programmable as low as 0.8V. The significant feature includes ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, there is an enable pin to further reduce power dissipation while shutdown. The RT9018A/B provides excellent regulation over variations in line, load and temperature. and provides a power OK signal to indicate if the voltage level of Vo reaches 90% of its rating value. z Ordering Information RT9018A/BPackage Type SP : SOP-8 (Exposed Pad-Option 1) QW : WDFN-10L 3x3 Lead Plating System P : Pb Free G : Green (Halogen Free and Pb Free) Z : ECO (Ecological Element with Halogen Free and Pb free) Output Voltage 10 : 1V/Adj 1K : 1.05V/Adj 12 : 1.2V/Adj 15 : 1.5V/Adj 18 : 1.8V/Adj 25 : 2.5V/Adj z z z z z Applications z z z Front Side Bus VTT (1.2V/3A) NoteBook PC Applications Motherboard Applications Marking Information For marking information, contact our sales representative directly or through a Richtek distributor located in your area.
