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) 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-25a (mini mold) applications package 1. portable equipment 2. cellular telephone, phs 3. cordless telephone 4. other battery-powered portable equipment pin assignment 13 5 2 4 sot - 25a (top view) 1 gnd 2 v dd 3 v out 4 nc 5 ce
