rp107x series output capacitor-less 200ma ldo no.ek-181-100119 200ma cmos ldo regulator the rp107x series are cmos-based ldo regulators featuring 200ma output. since the output capacitor and noise bypass capacitor are able to be reduced and the packages are small dfn(plp)1212-6, wlcsp-4-p5, and sc-88a, high density mounting on boards are possible. the input voltage (v in ) is as low as min.1.4v and the output voltage can be set from 1.0v. supply current is as low as 9.5 a compared to existing lines. the ce pin can switch the regulator to standby mode. features ? supply current (i ss ) typ. 9.5 a (i out =0ma) ? standby current (i standby ) typ. 0.1 a (in standby) ? dropout voltage (v dif ) typ. 0.27v (i out =200ma, v out =2.8v) ? ripple rejection (rr) typ. 60db (f=1khz, v out >2.5v) ? input voltage range (v in ) 1.4v to 5.25v ? output voltage range (v out ) 1.0v to 4.2v (internally fixed) ? output voltage accuracy 1% ? temp. coeff. of output voltage typ. 100ppm/ c ? line regulation typ. 0.02%/v ? fold-back protection circuit current limit typ. 50ma ? auto-discharge function d version ? packages wlcsp-4-p5, dfn(plp)1212-6, sc-88a, sot-23-5 block diagrams rp107xxxxb rp107xxxxd (without auto-discharge function) (with auto-discharge function) v dd gnd v out ce vref current limit v dd ce gnd v out vref current limit selection guides package quantity per reel part no. wlcsp-4-p5 5,000 pcs rp107z . xx . 1 . ? -tr-f dfn(plp)1212-6 5,000 pcs rp107k . xx . 1 . ? -tr sc-88a 3,000 pcs rp107q . xx . 2 . ? -tr-f sot-23-5 3,000 pcs rp107n . xx . 1 . ? -tr-f . xx . : specify the output voltage within the range 1.0v ( . 10 . ) to 4.2v ( . 42 . ) i in 0.1v steps. . ? : select from ( . b . ) without auto-discharge function or ( . d . ) with auto-discharge function packages (top view) t ypical characteristic wlcsp-4-p5 dfn(plp)1212-6 sc-88a sot-23-5 2 1 3 4 3 4 2 5 1 6 1 3 5 4 2 1 3 5 4 2 1 v dd 2 ce 3 gnd 4 v out 1 nc 2 gnd 3 ce 4 v dd 5 nc 6 v out 1 ce 2 nc 3 gnd 4 v out 5 v dd 1 v dd 2 gnd 3 ce 4 nc 5 v out rp107x30xx dropout voltage vs. output current 85 c 25 c -40 c 0 350 300 200 100 250 150 50 0 100 150 50 200 output current i out (ma) dropout voltage v dif (mv) applications ? power source for hand-held communication equipment, camera and vcrs ? power source for home appliances ? power source for battery-powered equipment
