The RT9166A-33GGL is a fixed 3.3V LDO regulator from Richtek, delivering up to 600mA. With a low dropout of 0.58V and 300 μA quiescent current, it is well-suited for power-sensitive applications. The SOT-223 package offers a balance of size and thermal performance, making it a versatile choice for consumer and industrial designs.
- Low Power Loss: 0.58V dropout at 600mA reduces heat generation.
- Low Standby Current: 300 μA quiescent current extends battery life.
- Noise Rejection: 55dB PSRR at 1kHz ensures clean output for sensitive loads.
- Versatile Package: SOT-223 is easy to solder and handles up to 1W dissipation.
Microcontroller Power Supplies
Provides a stable 3.3V rail for MCUs and digital logic. The 600mA output can power the MCU plus peripherals, while the low dropout ensures operation from a 5V rail.
Wireless Modules
Powers Wi-Fi, Bluetooth, and Zigbee modules requiring a clean 3.3V supply. The 55dB PSRR reduces noise coupling from the RF front-end.
LED Drivers
Regulates supply voltage for LED driver ICs, ensuring consistent brightness. The SOT-223 package handles moderate power dissipation.
Portable Instruments
Ideal for handheld meters and test equipment where a regulated 3.3V rail is needed from a 2-cell battery pack.
Set-Top Boxes
Provides a dedicated 3.3V supply for tuner and demodulator circuits, isolating them from digital switching noise.
