Preliminary RP1215 600mA Adjustable Output Voltage CMOS LDO Regulator General Description The RP1215 is designed for portable RF and wireless applicaiton with demanding performance and space requirements. The RP1215 performance is optimized for battery-powered systems to deliver low noise and low quiescent current. Regulator ground current increase only slightly in dropout, further prolonging the battery life. The RP1215 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, ciritical in hand-held wireless devices. The RP1215 has fast turn-on time typical 90us.The other features include ultra low dropout voltage, current limiting protection, and high ripple rejection ratio. Availabe in the 5-lead of SOT-23 package. Features Adjustable Output Voltage Ultra-Fast Response in Line/Load Transient Quick Start-Up (Typically 90µs) < 0.1µA Standby Current When Shutdown Low Dropout : 370mV @ 600mA Wide Operating Voltage Ranges : 2.5V to 5.5V TTL-Logic-Controlled Shutdown Input Low Temperature Coefficient Current Limiting Protection Thermal Shutdown Protection Only 1µF Output Capacitor Required for Stability High Power Supply Rejection Ratio RoHS Compliant and 100% Lead (Pb)-Free Ordering Information RP1215 Package Type B : SOT-23-5 Operating Temperature Range G : Green (Halogen Free with Comme-rcial Standard ) Output Voltage A : High Enable without Discharge B : High Enable with Discharge C : Low Enable without Discharge D : Low Enable with Discharge Applications Power source for battery-powered equipment Power source for cameras, camcorders, VCRs, PDAs, pagers, electronic data banks, and hand-held communication equipment Power source for appliances, which require higher voltage than that of batteries used in the appliances Note : Richpower Green products are : RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes.
