RT9011-SSGQWC

RT9011-SSGQWC Description

The RT9011-SSGQWC is a dual-channel linear regulator designed for high performance and efficiency in power management applications. Manufactured by Richtek USA Inc., this IC offers two fixed output voltages of 3.3V, each capable of delivering a maximum current of 300mA. The regulator is designed with a maximum input voltage of 5.5V, ensuring compatibility with a wide range of power sources. With a low dropout voltage of 0.33V at 300mA, the RT9011-SSGQWC maintains high efficiency even under low input-to-output voltage differentials.

The device features a quiescent current of only 80 µA, making it suitable for low-power applications. Its power supply rejection ratio (PSRR) ranges from 70dB at 100Hz to 38dB at 300kHz, providing excellent noise suppression and stability. The RT9011-SSGQWC is housed in a surface-mount 6WDFN package, which is both compact and thermally efficient, making it ideal for space-constrained designs.
