The RT9058-90GX from Richtek is a fixed 9V LDO linear regulator capable of 100mA output. It features a very low 5µA quiescent current and a dropout of just 0.5V at 10mA. With PSRR of 70dB at 100Hz, it delivers clean power for industrial and automotive applications in a compact SOT-89-3 package.
- Exceptional Efficiency at Light Load: 5µA quiescent current is ideal for battery-backed systems.
- Low Dropout: 0.5V at 10mA allows operation from nearly depleted batteries.
- High Ripple Rejection: 70dB at 100Hz filters mains-frequency noise.
- Robust Package: SOT-89-3 offers good thermal dissipation for continuous operation.
