The RTKA214023DE0000BU evaluation board provides a simple platform to evaluate the RAA214023. It contains all the important circuitry needed to characterize critical performance parameters. The RAA214023 is a low noise, high PSRR, low dropout voltage regulator. It accepts a input voltage range of 2.7V to 5.5V, and the output voltage can be programmed from 0.8V to 3.95V by means of voltage setting pins. To extend the output voltage range up to 5.5V-VDROPOUT, an external resistor divider feedback network can be used. The device can source a load current of up to 2A and has an output voltage accuracy of ±1.75% over line, load, and temperature.


  • Input Voltage Range: 2.7V to 5.5V
