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.
