| MITSUMI Regulator with ON/OFF MM3042 ~MM3045 N Regulator with ON/OFF Monolithic IC MM3042 ~MM3045 N Outline This IC is a low current consumption (2.5A typ.), small CMOS regulator ("L" Active type) with ON/OFF control. The output current capability has been increased from that of MM3051 ~ MM3055 V type regulators. Features 1. I/O voltage difference (MM3043L ~ MM3043V) 2. Current consumption 3. Output current (MM3045L ~ MM3045R) 4. Output voltage rank 5. Output ON/OFF control function 0.3V typ. (IO=60mA) 2.5A typ. (VIN=VOUT+1V) 100mA min. (VIN-VOUT=1.0V) 2.0~5.5V (0.1V step) High: OFF, Low: ON Package SOT-25 (Mini mold) Applications 1. Portable equipment 2. Cellular telephone, PHS 3. Cordless telephone 4.
