3. voltage regulators __________________________________________________________________________________ 26 xc62h series positive voltage regulators general description features the xc62h series are highly precise, low power consumption, positive voltage regulators, manufactured using cmos and laser trimming technologies. the series consists of a high pre - cision voltage reference, an error correction circuit, and an output driver with current limitation. by way of the ce function, with output turned off, the series enters stand-by. in the stand-by mode, power consumption is greatly reduced. sot-25 (150mw) and sot-89-5 (500mw) packages are avail- able. in relation to the ce function, as well as the positive logic xc62hr series, a negative logic xc62hp series (custom) is also available. maximum output current: 165ma (within maximum power dissipation, vout=3.0v) output voltage range: 2.0v to 6.0v in 0. 1v increments ( 1. 1v to 1.9v semi-custom ) highly accurate: setup voltage 2% ( 1% for semi-custom products ) low power consumption: typ 3 a [ vout=3.0, output enabled ] typ 0. 1 a [ output disabled ] output voltage temperature characteristics: typ 100ppm/ c line regulation: typ 0.2%/v ultra small package: sot-25 (150mw) mini-mold : sot-89-5(500mw) mini-power mold pin configuration pin assignment 1 2 3 sot-25 (top view) 4 5 v out v ss (nc) v in ce sot-89-5 (top view) ce v ss v in 1 (nc) v out pin number sot-25 sot-89-5 pin name function 1 4 (nc) no connection 22v in supply voltage input 3 3 ce chip enable 41v ss ground 55v out regulated output voltage block diagram v out v ss current limit + - v in voltage reference output control ordering information xc62h abcdef designator description designator description a true logic level at ce pin : r = positive p = negative ( custom ) b output voltage : 30 = 3.0v 50 = 5.0v e package type m = sot-25 p = sot-89-5 c0 d output voltage accuracy : 1 = 1.0% ( semi-custom ) 2 = 2.0% f device orientation : r = embossed tape ( right ) l = embossed tape ( left )
