1 / 12 page  RT9193 1 DS9193-09 March 2007 www.richtek.com 300mA, Ultra-Low Noise, Ultra-Fast CMOS LDO Regulator Marking Information For marking information, contact our sales representative directly or through a RichTek distributor located in your area, otherwise visit our website for detail. Ordering Information General Description The RT9193 is designed for portable RF and wireless applications with demanding performance and space requirements. The RT9193 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. A noise bypass pin is available for further reduction of output noise. Regulator ground current increases only slightly in dropout, further prolonging the battery life. The RT9193 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The RT9193 consumes less than 0.01 μA in shutdown mode and has fast turn-on time less than 50 μs. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. Available in the 5-lead of SC-70, SOT-23 and WDFN-6L 2x2 packages. Features Ultra-Low-Noise for RF Application Ultra-Fast Response in Line/Load Transient Quick Start-Up (Typically 50 μμμμμs) < 0.01 μμμμμA Standby Current When Shutdown Low Dropout : 220mV @ 300mA Wide Operating Voltage Ranges : 2.5V to 5.5V TTL-Logic-Controlled Shutdown Input Low Temperature Coefficient Current Limiting Protection Thermal Shutdown Protection Only 1 μμμμμF Output Capacitor Required for Stability High Power Supply Rejection Ratio Custom Voltage Available RoHS Compliant and 100% Lead (Pb)-Free Applications CDMA/GSM Cellular Handsets Battery-Powered Equipment Laptop, Palmtops, Notebook Computers Hand-Held Instruments PCMCIA Cards Portable Information Appliances Note : RichTek Pb-free and Green products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes. 100% matte tin (Sn) plating.
