r1500x series cmos voltage regulator voltage regulator with 500ma output current and 24v input voltage the currently available informat ion as of december 2009 is provided in this new product news. ek-151-08091101 maximum input voltage 24v the cmos type regulator has been introduced into the high input voltage area where only bipolar type could previously operate. adoption of dmos process the dmos (double diffused mos) transistor adopted by r1500x is characterized by a double diffusion structure which comprises a low density n-type (channel) diffused layer and a high density p-type (sources) diffused layer from the edge of the gate electrode. the r1500x series possess outstanding properties of high operating voltage and low on-resistance, which have been achieved by the channel length scaled down to submicron dimensions and decreased thickness of the gate oxide film. maximum operating ambient temperature 105c unlike ricoh?s conventional regulators, the operating ambient temperature range of the r1500x series is rated from -40 c to 105 c that makes it suitable for use in automotive and industrial applic ations involving higher temperatures. r 1 1 1 1 n r1111n r1111n r 1 5 1 5 x r1515x r 1 5 1 4 x r1514x 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 9 0 x r1190x r1190x r p 1 3 1 x rp131x rp131x r 1 1 7 1 j r1171j r1171j r 1 5 0 0 x r1500x r1500x r 1 5 0 1 x r1501x r1501x r 1 1 5 4 x r1154x r1154x r 1 1 5 0 h r1150h r1150h 0 5.25 6.5 6 8 18 24 36 0 200 400 600 500 800 50 150 300 1000 1500 1200 1400 1600 1800 2000 r 1 5 1 0 s r1510s r 1 1 7 1 s r1171s r1171s 16 output current (ma) maximum input voltage (v) c m o s t y p e h i g h i n p u t v o l t a g e a r e a cmos type high input voltage area cmos type high input voltage area c m o s t y p e l a r g e c u r r e n t r a n g e cmos type large current range cmos type large current range c m o s a r e a cmos area cmos area r 1 1 5 2 n e x t e r n a l o u t p u t t r a n s i s t o r t y p e r1152n external output transistor type r1152n external output transistor type 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 in 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 160 c. moreover, when the junction temperature decreases to a level below 135 c after the regulator has stopped, the regulator resumes to normal operation. as a result, the operation of the thermal sh utdown circuit causes the regulator repeat edly to turn off and on till the causes o f overheating are removed. as a consequence, a pulse shaped output voltage occurs. 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
