RTKA214020DE0010BU
Evaluation Board
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 V
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.
Key Features
• Input voltage range: 2.7V to 5.5V
• Output Voltage adjustable range: 0.9V to V
• Convenient shutdown mode function using jumper JP1
• Power-Good (PG) indication test point
