RTKA214023DE0000BU
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-V , an external resistor divider feedback
DROPOUT
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.
