Features
1. I/O voltage difference (MM3054 ~ MM3055 ) 25mV typ. (IO=1mA)
2. Current consumption 1.5µA typ. (VIN=VO+2V)
3. Output current 80mA min. (VIN
-
VOUT=2V)
4. Output voltage rank 1.7~5.5V (0.1V step)
5. Output ON/OFF control function High: ON, Low: OFF (MM3051H~MM3055F)
High: OFF, Low: ON (MM3051T~MM3055R)
