Description
The RAA214038 is an ultra-low noise, high PSRR, low-dropout regulator capable of sourcing up to 3A of load current with only 180mV dropout voltage. It operates from an input voltage of 1.1V for low-voltage applications to 6.5V
The LDO output voltage can be programmed from 0.8V to 3.95V using voltage setting pins on the IC in 50mV steps, eliminating the need for traditional external feedback resistors and saving PCB space. External feedback resistors can still be used for higher output voltage applications, allowing the output voltage to be programmed anywhere from 0.8V to 5.1V.
