Low-Ripple, Low-Saturation CMOS Regulators MM309X/MM310X Series

Low-Ripple, Low-Saturation CMOS Regulators

Monolithic IC MM309X, MM310X Series

Outline

This is a voltage regulator IC developed using the CMOS process.

Use of the CMOS process allows low current consumption, and it has superior ripple rejection ratio and

transient response compared to conventional CMOS process regulator ICs, making it ideal for use in portable

communications devices.

Ceramic capacitors can be used for the output capacitors.

Ideal for small, portable devices as SOT-25 and WLCSP are used for the package.
