ME6219 Power Management IC, CMOS Type Low Noise LDO Linear Regulator, 1.2–5.0V Output, 300mA, SOT23 / SOT89 Packages

The ME6219 is a Power Management IC designed as a CMOS type low-noise Low Dropout (LDO) linear regulator for noise-sensitive power rails. It operates with a maximum input voltage of 6.5V and provides fixed output voltage options from 1.2V to 5.0V.

Optimized for analog and RF-powered systems, the ME6219 delivers up to 300mA output current while maintaining low output noise and stable regulation. With a 62dB PSRR at 1kHz and controlled quiescent current of 65µA, it ensures clean and reliable power for sensitive loads.

The device is offered in multiple package options, including SOT23-5, SOT23-3, SOT89-3, and SOT89-5, allowing flexible integration across compact and higher-power PCB designs.
