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
45µA typ. (when not loaded, excluding the CE terminal current)
2. Super low consumption current (when off) 0.1µA typ.
3. High precision output voltage ±2%
4. Output current 150mA
5. Input/output voltage difference 0.23V typ. (Io=100mA, 3V output)
6. High ripple rejection ratio 80dB typ.
7. Built-in short-circuit restriction circuit 30mA typ.
8. Wide operating temperature range
-
30~+85°C
9. Output voltage 1.8~5.0V (0.1V step)
Applications
1. Constant voltage power supply for devices that use batteries
2. Constant voltage power supply for portable communications devices
3. Constant voltage power supply for household electronics products
