ts7900 series 3 - terminal fixed neg a tive voltage regulator 1 / 8 version: c 07 to - 220 ito - 220 to - 263 (d 2 pak) general description the ts7900 series of fixed output negative voltage regulators are intended as complements to the popular ts78 00 series device. these negati ve regulators are available in the same seven - voltage options as the ts7900 devices. in addition, one extra voltage option commonly employed in mecl systems is also available in the negative ts7900a series. available in fixed output voltage options from - 5 .0 to - 24 volts, these regulators employ current limiting, thermal shutdown, and safe - area compensation -- making them remarkably rugged under most operating conditions. with adequate heat sinking they can deliver output currents in excess of 1 ampere. this series is offered in 3 - pin to - 2 20 , i to - 220 & to - 263 package . features output voltage: - 5 & - 12v output current up to 1a no external components required internal thermal overload protection internal short - circuit current limiting output transistor safe - are a compensation output voltage offered in 4% tolerance ordering information part no. package packing ts79 xx cz c0 to - 220 50pcs / tube ts79 xx cz c0g to - 220 50pcs / tube ts79 xx ci c0 ito - 220 50pcs / tube ts79 xx cm rn to - 263 800pcs / 13 reel note: where xx denote voltage option not e: g denote for green product halogen free standard application circuit a common ground is required between the input and t he output voltages. the input voltage must remain typically 2.0v above the output voltage even during the low point o n the input ripple voltage. xx = these two digits of the type number indicate voltage. * = c in is required if regulator is located an appreciable distance from power supply filter. ** = co is not needed for stability; however, it does impro ve transient response. absolute maximum rating ( ta = 25 o c unless otherwise noted ) parameter symbol limit unit input voltage v in - 35 v power dissipation p d internal limited w junction temperature t j +150 o c storage temperature ra nge t stg - 65~+150 o c note: * follow the derating curve pin definition : 1. ground 2. input (tab) 3. output
