rp114 x series 300 ma ldo regulator no. ea - 236 - 1 60824 1 outline the rp114x series are cmos - based voltage regulator ics with high output voltage accuracy, low supply current, low dropout, and high ripple rejection. each of these voltage regulator ics consists of a voltage reference unit, an error amplifier, resi stors for setting output voltage, a short current limit circuit, a chip enable circuit, and so on. rp114x features a minimum input voltage from 1.4v and the output voltage, which can be set from 0.8v to 3.6v (in 0.1v step). the output voltage of these ics is internally fixed. these ics perform with low dropout voltage due to built - in transistor with low on resistance. low supply current and a chip enable function prolong the battery life of each system. the ripple rejection, line transient response and load transient response of the rp114 x series are excellent, thus these ics are very suitable for the power supply for hand - held communication equipment. since the packages for these ics are dfn(plp)1010 - 4, sc - 88a, sot - 23 - 5, therefore high density mounting of t he ics on boards is possible. features ? supply current ................................ ............................. typ. 50 a ? standby current ................................ ........................... typ. 0.1 a ? input voltage range ................................ ..................... 1.4v to 5.25v ? output voltage range ................................ .................. 0.8 v to 3.6 v (0.1v steps) ( for other voltages, please refer to mark specification table ). ? output voltage ac curacy ................................ .............. 1.0 % (v se t >2.0 v , t opt = 25 c ) ? temperature - drift coefficient of output voltage .......... typ. 80 ppm/ c ? dropout voltage ................................ ............................ typ. 0.2 5 v (i out = 300ma , v se t = 2.8 v) ? ripple rejection ................................ ........................... typ. 7 5 db (f = 1khz) ? line regulation ................................ ............................ typ. 0.02%/v ? package s ................................ ................................ .... dfn(plp)1010 - 4, sc - 88a, sot - 23 - 5 ? built - in fold back protection circuit ............................. typ. 6 0 ma (current at short mode) ? ceramic capacit ors are recommended to be used with this ic .... 1.0 f or more applications ? power source for portable communication equipment. ? power source for electrical appliances such as cameras, vcrs and camcorders. ? power source for battery - powered equipment.

(note: if additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for phase compensation, the operation might be unsta ble. because of this, test these ics with as same external components as ones to be used on the pcb.) pcb layout make v dd and gnd lines sufficient. if their impedance is high, noise pickup or unstable operation may result. connect a capacitor c1 with a c apacitance value as much as 1.0 f or more between v dd and gnd pin, and as close as possible to the pins. set external components, especially the output capacitor c2 , as close as possible to the ics, and make wiring as short as possible.
