MITSUMI
CMOS Switching Regulator (PWM controlled) MM3005~MM3010
CMOS Switching Regulator (PWM controlled)
Monolithic IC MM3005~MM3010
Outline
This IC is a PWM controlled switching regulator developed using the CMOS process. Low ripple and high
efficiency of 83% typ. (MM3005E) are achieved through PWM control. Further, output voltage is high
precision output ±2.4%.
Features
1. Ultra low consumption current 17.2µA typ. (during operation) (MM3005E)
2. High efficiency 83% typ. (MM3005E)
3. High precision output voltage ±2.4%
4. Wide operating temperature range -30°C~+85°C
5. Output voltage 2~5.5V (0.1V can be set in 0.1V steps)
Package
SOT-25A (Mini mold)
Applications
1. Mobile phones, PHS
2. Portable MD
3. Other battery-operated portable equipment
