The RTKA214020DE0010BU evaluation board provides a simple platform to evaluate the RAA214020. It contains all the important circuitry needed to characterize critical performance parameters.
The RAA214020 is a low noise, high PSRR, low dropout voltage regulator. It accepts an input voltage range of 2.7V to 5.5V and the output voltage can be programmed from 0.9V to VIN-VDROPOUT by means of a resistor divider feedback network. The device can source a load current of up to 2A and has an output voltage accuracy of ±1.25% over line, load, and temperature.
