The RT9166A-36GXL is a fixed 3.6V low dropout linear regulator from Richtek, capable of delivering up to 600mA of output current. It features a typical dropout voltage of just 0.58V at full load, enabling efficient operation from a variety of input sources. With a low quiescent current of 300 μA and a power supply rejection ratio of 55dB at 1kHz, this regulator is well-suited for battery-powered and noise-sensitive applications. Housed in a compact SOT-89-3 package, it offers a reliable and space-saving power management solution.
- High Efficiency with Low Dropout: The 0.58V typical dropout voltage at 600mA allows operation from input voltages close to the output, reducing power dissipation and improving system efficiency.
- Extended Battery Life: The low 300 μA quiescent current minimizes current draw during standby, making it ideal for battery-powered devices.
- Clean Power Delivery: With 55dB PSRR at 1kHz, it effectively filters out power supply noise, ensuring stable operation for sensitive analog and digital circuits.
- Robust Current Capability: The 600mA output current rating provides ample headroom for powering multiple ICs or modules from a single regulator.
Powering 3.6V Logic and Memory
The fixed 3.6V output is suitable for powering legacy logic families, memory modules, and other ICs that require a 3.6V supply rail. The 600mA current capability ensures reliable operation.
Battery-Powered Devices with Higher Voltage Rails
For devices using Li-ion batteries that need a regulated 3.6V output, this LDO provides a stable supply while its low 300 μA quiescent current helps conserve battery power.
Noise-Sensitive RF and Analog Front-Ends
The 55dB PSRR at 1kHz helps maintain a clean supply for RF transceivers, PLLs, and precision analog circuits, reducing the risk of noise-induced performance degradation.
Post-Regulation for Switching Converters
Use the RT9166A-36GXL after a DC-DC converter to provide a low-noise, precisely regulated 3.6V rail, reducing ripple and switching noise for sensitive loads.
