1 / 15 page  RT9172 1 DS9172-14 March 2007 www.richtek.com Features Low Dropout Voltage Low Ground Pin Current Load Regulation of 0.4% at 3A 0.5mA Quiescent Current in Shutdown Mode Guaranteed Output Current of 3A DC Available in TO-263 and TO-220 Packages Output Voltage Accuracy ±±±±±1.5% Error Flag Indicates Output Status Sense Option Improves Better Load Regulation Extremely Low Output Capacitor Requirements Over-Temperature/Over- Current Protection RoHS Compliant and 100% Lead (Pb)-Free Pin Configurations Applications Microprocessor Power Supplies GTL, GTL+, BTL, and SSTL Bus Terminators Power Supplies for DSPs SCSI Terminator Post Regulators High Efficiency Linear Regulators Battery Chargers Other Battery Powered Applications 3A Fixed Output Voltage LDO Regulator Ordering Information General Description The RT9172 series of low-dropout linear regulators operate from a +2.25V to +6.0V input supply. A wide range of preset output voltage options is available. These low dropout linear regulators respond very fast to step changes in load, which are suitable for low voltage microprocessor applications. The RT9172 uses an internal PMOS as the pass device, which does not cause extra GND current in heavy load and dropout condition. The shutdown mode of low operation current makes the IC suitable for power-saving systems. The other features include current limiting and over temperature protection.
