ME6401 Dual Channel CMOS LDO Linear Regulator, High Speed, High PSRR, High Accuracy, 1.2–5.0V Output, 300mA, SOT23-6 Package

The ME6401 is a dual-channel CMOS LDO linear regulator designed for high-precision, low-noise applications. Each channel provides an output voltage range of 1.2V to 5.0V, delivering up to 300mA output current per channel. Its high PSRR of 70dB @1kHz ensures minimal ripple from the input supply, making it ideal for sensitive analog and RF circuits.

Available in a compact SOT23-6 package, the ME6401 suits space-constrained designs while maintaining high efficiency and fast transient response.
