RS3219-1.2YF5

RS3219 Low Power, Low Dropout, 300-mA Low-Noise, Low-IQ LDO FEATURES DESCRIPTION  Low Output Noise The RS3219 series low-power, low-dropout, CMOS LDO operate from 1.7V to 7.5V input voltage that can supply up to 300 mA of output current. Designed to meet the requirements of RF and analog circuits, the RS3219 series device provides low noise, high PSRR, low quiescent current, and low line and load transient response. The device is designed to work with a 1-µF input and a 1-µF output ceramic capacitor. Other features include a 10nA logic-controlled shutdown mode and thermal shutdown protection. The RS3219 series is available in Green SOT23-3, SOT23-5 and UTDFN-1x1-4 packages. It operates over an ambient temperature range of -40°C to +85°C.  Low Dropout Voltage  Thermal-Overload Protection  10nA Logic-Controlled Shutdown  Available in Multiple Output Voltage Versions  Fixed Outputs of 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V,3.3V APPLICATIONS  Cellular Telephones  Camera Modules  Sensors  HiFi Audio Radio Transceivers Device Information (1)  PLL/Synthesizer, Clocking PART NUMBER  Medium-Current, Noise-Sensitive Applications RS3219 (1) UTDFN-1×1-4 BODY SIZE (NOM) 1.00mm×1.00mm SOT23-3 1.60mm×2.92mm SOT23-5 1.60mm×2.92mm PACKAGE For all available packages, see the orderable addendum at the end of the data sheet.
