r1150h series voltage regulator (with wide in put voltage range) with reset no.ea-081-111027 1 outline the r1150h series are cmos-based voltage regulator (vr) ics equipped with a voltage detector (v det ). vr function of the r1150hxxxx has featur es of low dropout voltage, high ou tput voltage accura cy, and ultra-low supply current. each of the r1150hxxxa series includes also a chip enable circuit. the output of built-in voltage detector is nch open drain type. the r1150hxxxc/d have a pin for connecting external capacitor to set a certain reset delay time instead of chip enable control pin. the regulator output voltage and the detector threshold volt age are fixed in the ic, output voltage accuracy is 2.0%, while detector threshold accuracy is 2.5 %. the r1150hxxxa (with chip enable function) and r1150hxxxc series can supervise input voltage by the built-in detector. r1150hxxxb can supervise sense pin voltage by the built-in detector. r1150hxxxd type can supervise v out voltage, or regulator output voltage of this ic itself. since the package for these ics is the sot-89-5 package, high density mounting of the ics on boards is possible. features ? supply current ..................................................typ. 7.0 a ? input voltage .....................................................max. 24.0v ? output voltage (vr)..........................................2.1v to 14.0v (0.1v steps) ( for other voltages, please refer to mark informations.) ? detector threshold voltage (v det ) ....................2.0v to 15.0v (r1150hxxxb/c/d) 2.3v to 15.0v (r1150hxxxa) ? output voltage accuracy ...................................2.0% (vr), 2.5% (vd) ? output current ..................................................min. 150ma (v out =5.0v) ? package ............................................................sot-89-5 ? built-in fold-back protec tion circuit .................typ. 45ma (current at short mode) ? built-in thermal shutdown circuit (vr) ............thermal shutdown temperature ; typ. 150 c released temperature ; typ. 120 c ? monitoring v dd voltage ......................................r1150hxxxa/c ? monitoring sense pin ( sense) voltage ............r1150hxxxb ? monitoring v out pin voltage...............................r1150hxxxd applications ? power source and reset circuit for cameras, videos and mobile telecommunication equipment. ? power source and reset circuit for battery-operated equipment. ? power source and reset circuit for home appliances.

r1150h 29 refer to the following formula for setting the voltage of output and detective value. (v out 0.975) ? (-v det 1.10) > 0.2 thermal shutdown thermal shutdown function is included in the r1150 hxxxa/b/c/d series, when the junction temperature is equal or more than +150c (typ.), the operation of regulator would stop. after that, when the junction temperature is equal or less than +120c (typ.), the oper ation of regulator would restart. unless the cause of rising temperature would remove, the regulator repeats on and off, and output waveform would be like consecutive pulses. chip enable circuit do not make voltage level of chip enable pin keep floating level, or in between v ih and v il . unless otherwise, output voltage would be unstable or indefinite, or unexpected current would flow internally. output delay time for release v det in the r1150hxx1c/d can set an output delay time for release voltage detector with connecting a capacitor to c d pin. when an input voltage (in the case of r1150hxx1c) or an output voltage (in the case of r1150hxx1d) surpasses the release voltage of its voltage detector (+v det ), the capacitor which is connected to c d pin is started to be charged, as a result, c d pin voltage rises. when the c d pin voltage surpasses c d pin threshold voltage, the output voltage of the voltage detector outputs ?h?. input voltage or output voltage c d pin voltage output voltage output delay time (tplh) gnd gnd c d pin threshold voltage released voltage (+v det ) output delay time for release voltage detector can be calculated with the next formula: t plh =1.25/200 10 9 c d (sec) input transient response if the input transient speed is equal or faster than 80mv/ s and the transient level difference is equal or more than 1.5v, the output response may be extremely worse than normal operation. in that case, add a capacitor between v in and gnd, and make the transient speed of v in slower than 80mv/s.
