GND RT9013 500mA, Low Dropout, Low Noise Ultra-Fast Without Bypass Capacitor CMOS LDO Regulator General Description Features Wide Operating Voltage Ranges : 2.2V to 5.5V The RT9013 is a high-performance, 500mA LDO regulator, Low Dropout : 250mV at 500mA offering extremely high PSRR and ultra-low dropout. Ideal Ultra-Low-Noise for RF Application for portable RF and wireless applications with demanding Ultra-Fast Response in Line/Load Transient performance and space requirements. Current Limiting Protection The RT9013 quiescent current as low as 25A, further Thermal Shutdown Protection prolonging the battery life. The RT9013 also works with High Power Supply Rejection Ratio low-ESR ceramic capacitors, reducing the amount of board Output Only 1F Capacitor Required for Stability space necessary for power applications, critical in hand- TTL-Logic-Controlled Shutdown Input held wireless devices. RoHS Compliant and 100% Lead (Pb)-Free The RT9013 consumes typical 0.7A in shutdown mode Applications and has fast turn-on time less than 40s. The other features CDMA/GSM Cellular Handsets include ultra-low dropout voltage, high output accuracy, Portable Information Appliances current limiting protection, and high ripple rejection ratio.
