Overview
Description
The RAA214023 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 voltage can be programmed from 0.8V to 3.95V by means of the PCB layout, eliminating the need for traditional external feedback resistors. To extend the output voltage range up to 5.5V-VDROPOUT external feedback resistors can still be used. RAA214023 is pin-to-pin compatible with TPS7A83 family.
Features
- Input Voltage Range: 2.7V to 5.5V
- Max Output Current: 2A

- Low RMS output noise: 6.5μVRMS (10Hz to 100kHz)
- Two Output Voltage Configurations
- High PSRR
- Output Voltage Accuracy ±1.75% over line, load,and temperature
- Fast startup: 200μs at VHEADROOM = 3.7V
- Typical shutdown current: 200nA at +125°C
- Overvoltage indication, and overcurrent and over-temperature fault protection
