da9168.000 2 september 2003 1 (13) mas9168 150 ma ldo voltage regulator ic ? only 15.5 a ground pin current at 1 ma load current ? good transient performance ? low dropout voltage ? low noise ? enable/disable control ? stable with low-esr output capacitors description mas9168 ldo voltage regulator is optimized for operation at low ground pin current: even at 50 ma load current its ground pin current is only 40 a. this combined with the good overall performance makes mas9168 very suitable for providing continuous supply in low power circuits. the performance of mas9168 benefits applications where standby periods are long and where long battery lifetime is essential. in addition to the low ground pin current, mas9168 excels in dropout voltage (220 mv typical at 150 ma). even though mas9168 does not use an external bypass capacitor, the noise level (100 hz? 100 khz) is only 70 vrms with 1 f output capacitor. the equivalent series resistance (esr) range of output capacitors that can be used with mas9168 is very wide. this esr range from zero up to a couple of ohms combined with no minimum output current requirement makes the usage of mas9168 easier and low in cost. enable/disable pin allows mas9168 to be turned off and on. in order to save power the device enters the sleep mode when the regulator is disabled. an internal thermal protection circuit prevents the device from overheating. also the maximum output current is internally limited. features applications ? extremely low current consumption ? good transient performance ? output accuracy < 3.3% ? internal thermal shutdown ? short circuit protection ? thin sot (tsot-5) or wl-csp package ? several output voltage options available, see ordering information p. 12 ? continuously working low power circuits ? wlan chip sets ? digital circuits ? real-time clocks (rtc) ? srams ? cmos backup power ? cellular phones ? portable systems ? smoke detectors this is preliminary information on a new product unde r development. micro analog systems oy reserves the right to make any changes without notice.

da9168.000 2 september 2003 8 (13) application information auto-discharge function mas9168 does not feature an auto-discharge function. the voltage in vout pin, when mas9168 is turned off, depends on the load circuits leakage: if the load has big leakage current, vout rapidly drops to the value 0 v, but if the leakage current is non-existing, vout pin stays in v out(nom) value. calculating maximum power dissipation maximum power dissipation of the package may limit output current or input voltage, which can be used, especially with the combination of low output voltage and high input voltage. the power dissipation can be calculated by using the formula: () gnd in out out in d i * v i * v v p + ? = it shall not exceed the maximum power dissipation, allowed by the package: ja a jmax dmax r t t p ? = where t jmax is maximum junction temperature (t jmax = 125c), t a is ambient temperature and r ja is junction-to-ambient thermal resistance of the package. when assumed that: t a = +55c, v out = 1.8 v, v in = 5.0 v and used package is tsot-5 the equation yields: w 0.338 c/w 207 c 55 c 125 p dmax = ? = from which can be calculated: ma 106 v v p i out in dmax outmax = ? = v in * i gnd is negligible and can be omitted. consequently, it can be seen that under these conditions the average out put current should not exceed 106 ma.
