The Richtek RT9166A-13GG is a fixed-output low dropout linear regulator delivering a stable 1.3V supply at up to 600mA. Its low 0.58V dropout voltage and 300 μA quiescent current make it an efficient choice for battery-powered and portable applications. Housed in a compact SOT-223 package, it offers a reliable power solution for noise-sensitive circuits.
- Efficient Power Conversion: The low 0.58V dropout voltage maximizes efficiency by allowing operation with a smaller input-to-output voltage difference.
- Extended Battery Life: A low 300 μA quiescent current minimizes current draw from the battery in standby or light-load conditions.
- Clean Output for Sensitive Loads: With 55dB PSRR at 1kHz, it effectively suppresses input noise, ensuring a stable supply for analog and RF circuits.
- Robust Thermal Performance: The SOT-223 package provides a low thermal resistance path, enabling reliable operation at full 600mA load.
Low-Voltage Digital Core Power
Power 1.3V digital cores in FPGAs, ASICs, or microcontrollers from a higher system rail. The 600mA current capability and low dropout voltage ensure stable operation even when the input supply dips.
Battery-Powered Portable Devices
In battery-operated equipment, the 300 μA quiescent current helps extend battery life. The low dropout voltage allows efficient use of the battery's voltage range before it needs recharging.
Noise-Sensitive Analog Circuits
With a PSRR of 55dB at 1kHz, this regulator helps filter power supply noise, making it suitable for powering sensitive analog circuits like op-amps, ADCs, and PLLs.
Post-Regulation for Switching Converters
Use the RT9166A-13GG after a DC-DC converter to provide a clean, low-noise 1.3V rail. The low dropout voltage minimizes power dissipation in the linear stage.
