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.
Features
1. Super low consumption current
2. Super low consumption current (when off)
3. High precision output voltage
4. Output current
5. Input/output voltage difference
6. High ripple rejection ratio
7. Built-in short-circuit restriction circuit
8. Wide operating temperature range

· Output Capacitor
Ceramic Capacitor 2.2µF (Output voltage : 2.5~5.0V)
Ceramic Capacitor 4.7µF (Output voltage : 1.8~2.5V)
· Input Capacitor
Ceramic Capacitor 2.2µF
Note
1. The output capacitor is required between output and GND to prevent oscillation.
2. The ESR of capacitor must be defined in ESR stability area.
It is possible to use a ceramic capacitor without ESR resistance for output.
The ceramic capacitor must be used more than 2.2µF or 4.7µF and B temperature characteristics.
3. The wire of VCC and GND is required to print full ground plane for noise and stability.
The input capacitor must be connected a distance of less than 1cm from input pin.
