150mA Dual Regulator
Monolithic IC MM3248 Series
Outline
This IC is a 2-circuit type of MM324x series that is a low saturation regulator IC with 150mA output realizing
low current consumption, low noise, and high ripple rejection using a CMOS process. The output voltage of
the regulator is fixed and can be programmed between 1.5V and 5.0V upon request. it provides a switch pin
to control each output and is an ideal IC for the portable equipment.
Features
1. Current consumption (during off-state) 0.02µA
2. High accuracy output voltage ±1.0%
3. Dropout voltage 0.13V typ. (Io=100mA)
4. High ripple rejection 77dB typ.
5. Operating temperature range
-
40 to +85°C
6. Output voltage 1.5 to 5.0V (0.1V steps)
7. Output capacitor 0.1µF (Ceramic)
