DESCRIPTION
The RS3219 series low-power, low-dropout, CMOS LDO operate from 2.5V to 5.5V input voltage that can supply up to 300 m A 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...
