micrel, inc. mic528 2 february 12 , 2014 10 revision 1.1 detailed description the MIC5282 voltage regulator accepts a 6v to 120v input and has a n ultra - low 6a typical quiescent current while offering an excellent line transient res ponse and psrr . these features make it ideal for harsh, noisy environments. all options of the device offer 50 ma of output current. the MIC5282 ymm and MIC5282 ymme offer an adjustable output voltage from 1.27v to 5.5v . the MIC5282 - 3.3ymme and MIC5282 - 3.3ymm offer fixed 3.3v outputs and t he MIC5282 - 5.0ymme and MIC5282 - 5.0ymm offer fixed 5.0v outputs . t he ymme packaged devices feature a heat slug to more effectively remove heat from the die . application s information thermal protection MIC5282 has internal ther mal shutdown to protect it from excessive heating of the die . when the junction temperature exceeds approximately + 1 5 5 c, the output is disabled and the device begins to cool down . the device turns back on when the junction temperature cools by 1 5 c. this will result in a cycled output during continuous thermal - overload conditions. current limit MIC5282 features output current - limit protection. the output sustains a continuous short circuit to gnd without damage to the device , but thermal shutdown often re sults. input capacitor connect a 1.0f capacitor from vin to gnd. micrel recommends the c5750x7r2e105m, 1.0f, 250v capacitor made by tdk. when using a different capacitor, assure that the voltage rating of the capacitor exceeds any potential transient. cp srr capacitor connect a 0.1 f capacitor from cpsrr to gnd to maintain high power supply rejection . the voltage rating of the capacitor must be at least 14v . output capacitor connect a 10f capacitor from vout to gnd. assure that the voltage rating of the capacitor exceeds the designed output voltage of the MIC5282 . output voltage setting for th e MIC5282 ymme and MIC5282 ymm , v out is programm ed from 1.2 7 v to 5. 5 v using : ? ? ? ? ? ? + = 1 r2 r1 v v ref out w here v ref = 1.2 7 v , and r1 and r2 are shown in the typical appl ications circuit. thermal measurements it is always wise to measure an ic?s case temperature to make sure that it is within operating limits , but it is easy to get erroneous results. t he standard thermal couple that comes with many voltage meter s uses a la rge wire gauge that behaves like a heat - sink, resulting in artificially low case temperature measurement s . use a thermocouple of 36- gauge wire or smaller, such as the omega (5sc - tt - k - 36- 36), to minimize the heat - sinking effect. also, apply thermal compound to maximize heat transfer between the ic and the thermocouple . an infrared thermometer is a recommended alternative. the ir thermometer from optris has a 1mm spot size, ideal for monitoring small surface mount packages. also, the optional stand makes it easy to keep the beam on the ic for long periods of time.
