有关 RAA214045 的资源
描述
The RAA214045 is an ultra-low noise, high Power Supply Rejection Ratio (PSRR), low-dropout regulator capable of sourcing up to 4A of load current with only 250mV 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 0.5V to 3.65V using voltage setting pins on the IC in 50mV steps without requiring traditional external feedback resistors and while saving PCB space. External feedback resistors can be used for higher output voltage applications, allowing the output voltage to be programmed anywhere from 0.5V to 5.1V.
The RAA214045 has an ultra-low output noise and high PSRR without a feed-forward capacitor. It only requires a single 1µF noise-reduction capacitor to achieve 7µVRMS output noise, making it great for noise-sensitive and space-constrained applications.
