高精度线性稳压器RS3219

GENERAL 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 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.
