rp106x series 400ma 1v input ldo no.ek-180-091101 400ma cmos ldo regulator the rp106x series are cmos-based ldo regulators featuring 400ma output. the input voltage as low as min. 1.0v and the output voltage can be set from 0.7v. the output voltage accuracy has been improved to 0.8% and due to a built-in transistor with low on-resistance of 0.55 (at v out =1.5v), rp106x provides a low dropout voltage. the ce pin can switch the regulator to standby mode. in addition to sot-23-5 and sc-88a packages, a 0.69mm square wlcsp-4-p5 package and a 1.2mm square dfn(plp)1212-6 package are also available. features ? supply current (i ss ) typ. 48 a (v in =set v out +1v) ? standby current (i standby ) typ. 0.1 a (same as above, ce="l") ? dropout voltage (v dif ) typ. 0.22v (i out =400ma, v out =1.5v) ? ripple rejection (rr)typ. 60db (f=10khz) ? input voltage range (v in ) 1.0v to 3.6v ? output voltage range (v out )0.7v to 1.8v (internally fixed) ? output voltage accuracy 0.8% ? temp. coeff. of output voltage typ. 60ppm/ c ? line regulation typ. 0.10%/v ? fold-back protection circuit current limit typ. 110ma ? auto-discharge function d version ? packages wlcsp-4-p5, dfn(plp)1212-6, sc-88a, sot-23-5 ? ceramic capacitors can be used 1 f or more (the above shows specification at topt=25 c. design assurance value at -40 c < = < = c is also available. for details, please refer to the datasheet.) block diagrams rp106xxxxb rp106xxxxd (without auto-discharge function) (with auto-discharge function) v dd gnd v out ce vref current limit v dd gnd v out ce vref current limit selection guides package quantity per reel part no. wlcsp-4-p5 5,000 pcs rp106z . xx . 1 . ? -tr-f dfn(plp)1212-6 5,000 pcs rp106k . xx . 1 . ? -tr sc-88a 3,000 pcs rp106q . xx . 2 . ? -tr-f sot-23-5 3,000 pcs rp106n . xx . 1 . ? -tr-f . xx . : specify the output voltage within the range 0.7v ( . 07 . ) to 1.8v ( . 18 . ) 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 rp106x12xx dropout voltage vs. output current 0 350 250 300 150 200 100 50 0 300 100 150 200 400 250 50 350 output current i out (ma) dropout voltage v dif (mv) t opt =85 c t opt =25 c t opt =-40 c applications ? power source for hand-held communication equipment, camera and vcrs ? power source for home applianc es and digital home appliances ? power source for battery-powered equipment
