RAA214035 Ultra-Low Dropout, Low VIN, Ultra-Low Noise, High PSRR, 3A LDO Datasheet The RAA214035 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 very low voltage applications to 6.5V. The LDO output voltage can be programmed from 0.5V to 3.65V 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 0.5V to 5.1V. The RAA214035 has an ultra-low output noise and high PSRR without a feed-forward capacitor.
