The RT9198-30GQW from Richtek is a fixed 3.0V LDO regulator offering 300mA output current. With a dropout voltage of 0.33V and quiescent current of 130 μA, it balances efficiency and performance. The ultra-compact 6-WDFN (2x2mm) package is perfect for miniaturized electronic designs.
- Space-Saving Design: 2x2mm WDFN package reduces PCB area by up to 50% vs. SOT-23.
- Low Power Loss: 130 μA quiescent current and 0.33V dropout minimize wasted energy.
- Excellent Noise Rejection: PSRR of 60dB at 100Hz protects sensitive loads.
- Thermal Efficiency: Exposed pad in WDFN improves heat dissipation for 300mA loads.
Compact Wearable Devices
The 2x2mm WDFN package is ideal for smartwatches and fitness bands, providing a stable 3V rail for sensors and MCUs.
High-Density PCB Designs
