Overview
Description
The RAA214035 is an ultra-low noise, high PSRR, low dropout regulator capable of sourcing up to 3A of load current with only 180mV dropout voltage. It operates from an input voltage of 1.1V for very low voltage applications to 6.5V. The RAA214035 has an ultra-low output noise and high PSRR without a feed-forward capacitor. It only requires a single 1µF noise-reduction capacitor to achieve 7µVRMS output noise, making it great for noise-sensitive and space-constrained applications.
Features
- Maximum dropout: 180mV at 3A with BIAS
- Output voltage accuracy: ±1%
- Ultra-low output noise: 7μVRMS
- Input voltage range:
- Without BIAS: 1.4V to 6.5V
- With BIAS: 1.1V to 6.5V
- Output voltage range:
- Using voltage set pins: 0.5V to 3.65V
- Using external FB resistors: 0.5V to 5.1V
- BIAS voltage range: 3V to 6.5V
- Max operating load current: 3A
- High PSRR at VHEADROOM = 1.7V
- 100kHZ: 35dB at 3A
- Enable control and power-good indication
- Overcurrent, short-circuit and over-temperature fault protection
- Excellent load transient response
