r1514x series cmos voltage regulator voltage regulator with 150ma output current and 36v input voltage the currently available informat ion as of december 2009 is provided in this new product news. ek-152-091101 voltage regulator with 150ma output and 36v input voltage maximum input voltage 36v the cmos type regulator has been introduced into the high input voltage area where only bipolar type could previously operate. the r1514x series hav e achieved the absolute maximum rating as high as 50v (peak input voltage: 60v < 200ms). low supply current during operation: 9 a this value represents the world?s lowest supply current of regulators with an input voltage of 36v. a battery saving system can be built, because the supply current is low in the operating mode as well as in standby mode. maximum operating ambient temperature 105 c unlike ricoh?s conventional regulators, the operating ambient temperature range of the r1514x series is rated from -40 c to 105 c that makes it suitable for use in automotive and industrial applic ations involving higher operating temperatures. output current (ma) maximum input voltage (v) c m o s h i g h i n p u t v o l t a g e a r e a cmos high input voltage area cmos high input voltage area c m o s h i g h c u r r e n t a r e a cmos high current area cmos high current area c m o s a r e a cmos area cmos area r 1 1 1 1 n r1111n r1111n r 1 1 1 4 x r1114x r1114x r p 1 0 0 x rp100x rp100x r p 1 0 2 x rp102x rp102x r 1 1 7 2 x r1172x r1172x r 1 1 7 0 x r1170x r1170x r 1 1 7 1 j r1171j r1171j r 1 5 1 4 x r1514x r1514x r 1 5 1 5 x r1515x r1515x a b s o l u t e m a x i m u m r a t i n g 5 0 v ( p e a k i n p u t v o l t a g e 6 0 v ) absolute maximum rating 50v (peak input voltage 60v) 0 5 6 8 18 36 0 200 400 600 800 50 150 300 1000 1200 1400 1600 1800 2000 w i t h e x t e r n a l o u t p u t t r a n s i s t o r with external output transistor r 1 1 5 2 n r1152n r1152n thermal shutdown circuit the thermal shutdown circuit shown in the block diagram detects an increase in temperature, stops operation, and protects the r egulator from being damaged by a short circuit of the output pin (v out ) and ground pin (gnd). the thermal shutdown circuit stops operation of the regulator when the junction temperature of the regulator exceeds 150 c. moreover, when the junction temperature decreases to a level below 125 c after the regulator has stopped, the regulator resumes to normal operation. as a result, the operation of the thermal s hutdown circuit causes the r egulator repeatedly to turn off and on till the causes o f overheating are removed. as a consequence, a pulse shaped output voltage occu rs. care should be taken to prevent this situation. in the datasheet it is shown as a t hermal shutdown detection temperature (t tsd ) and a thermal shutdown release temperature (t tsr ). products with a built-in thermal shutdown circuit r1150h r1154x r1170x r1171x r1172x r1173x r1190x r1191x r1500x r1501x r1514x r1515x rp131x rp170x rp171x
