RS3219-3.3YC5

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 2.5V to 5.5V 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 (no separate noise bypass capacitor required). An external noise bypass capacitor connected to the device’s BP pin can further reduce the noise level. Other features include a 10nA logic- controlled shutdown mode, foldback current limit and thermal shutdown protection. The RS3219 series is available in Green SOT23-3, SOT23-5 and SOT353 (SC70-5) packages. It operates over an ambient temperature range of 40°C to +85°C.  Low Dropout Voltage  Thermal-Overload Protection  Output Current Limit  10nA Logic-Controlled Shutdown  Available in Multiple Output Voltage Versions  Fixed Outputs of 1.5V,1.8V,2.5V,3.3V APPLICATIONS • Cellular Telephones • Camera Modules • Sensors • • HiFi Audio Radio Transceivers PLL/Synthesizer, Clocking • Medium-Current, Noise-Sensitive Applications Functional Block Diagram Current Limit IN 1.2V VREF OUT Error amp Internal Controller Thermal Shutdown EN BP GND REV A.3 1 Copyright © 2017, RUNIC Technology www.run-ic.com RS3219 Pin Configuration and Functions (Top View) IN 1 GND 2 EN 3 5 OUT 4 BP SOT23-5/SOT353(SC70-5) SOT353 (SC70-5) / SOT23-5 NUMBER DESCRIPTION I/O NAME 1 IN I Regulator Input.
