Regulator with ON/OFF MM3042 ~MM3045 N
Regulator with ON/OFF
Monolithic IC MM3042 ~MM3045 N
Outline
This IC is a low current consumption (2.5µA 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
