Description
The RAA214020 is an ultra-low noise, high-PSRR, low-dropout voltage regulator. The LDO operates from an input voltage range of 2.7V to 5.5V and can source a maximum 2A load. The output is adjustable with external feedback resistors anywhere from 0.9V up to 5.5V-V DROPOUT.
The RAA214020 has a low output noise of 6.3μVRMS typical and high PSRR which makes it well-suited for post-regulation in low-noise applications.
The operating quiescent current is typically 195μA and drops to a couple nanoamps typical at room temperature when in shutdown making it great for portable applications.
The LDO features ±1.5% output voltage accuracy (over line, load, and temperature), input UVLO with hysteresis, enable control, internal current limit, thermal shutdown protection with hysteresis, power-good indication, and fast start-up. Additionally, the LDO is stable with a minimum 22μF ceramic output capacitor and is available in a 10 Ld 3mm x 3mm DFN package great for compact system boards.
