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)
0.3V typ. (I
O
=60mA)
2. Current consumption
2.5A typ. (V
IN
=V
OUT
+1V)
3. Output current (MM3045L ~ MM3045R)
100mA min. (V
IN
-V
OUT
=1.0V)
4. Output voltage rank
2.0~5.5V (0.1V step)
5. Output ON/OFF control function
High: OFF, Low: ON
SOT-25 (Mini mold)
Applications
Package
1. Portable equipment
2. Cellular telephone, PHS
3. Cordless telephone
4. Other battery-powered portable equipment
