The RT9198-28GY is a fixed 2.8V LDO linear regulator from Richtek, delivering up to 300mA with a dropout of only 0.33V. Its 130 μA quiescent current and excellent PSRR make it a preferred choice for battery-powered and noise-sensitive designs. The SC-82 package offers a compact solution for space-constrained applications.
- Power Efficiency: Low 130 μA quiescent current reduces idle power draw.
- Superior Ripple Rejection: 60dB PSRR at 100Hz ensures clean output for analog circuits.
- High Current Density: 300mA output in a small SC-82 package.
- Low Dropout: 0.33V dropout enables operation from low input voltages.
