device description the zsd5030 dual fixed positive voltage regulators feature internal circuit current limit and thermal shutdown making the devices almost impossible to destroy. the devices are available in zetex small outline sm8 package, ideal for applications where space saving is important. two configurations are available - common and isolated - as represented in the schematic diagrams below. the devices feature output voltages of 5 and 3 volts each capable of delivering up to 200ma. the sm8 package allows up to 2.25w power dissipation for each regulator. the devices are suited to local voltage regulation applications, where problems could be encountered with distributed single source regulation, as well as more general voltage regulation applications. the zsd5030 devices show performance characteristics superior to other local voltage regulators. the initial output voltage is maintained to within 2.5% with a quiescent current of typically 350 m a. output voltage change with input voltage and load current is much lower than competitive devices. the zsd5030 devices are completely stable with no external components. the devices will shut down under thermal overload conditions but as the device cools, regulation will restart until thermal overload reoccurs. features small outline sm8 package two device configurations 5v and 3v output output current up to 200ma tight initial tolerance low quiescent current -55 to 125 c temperature range no external components internal thermal shutdown internal short circuit current limit 2.25w per device dual fixed positive 5 and 3 volt local voltage regulator issue 1 - november 1995 ZSCD5030 zsxd5030 connection table pin common isolated 1 vin(5) vin(5) 2 -- 3 vin(3) vin(3) 4 -- 5 gnd gnd(3) 6 vout( 3) vout( 3) 7 -gnd(5) 8 vout( 5) vout( 5) configuration cx see diagram page 4 - 6 = connection options vin(5) vin(3) vout(5) vout(3) gnd vin(5) vin(3) vout(5) vout(3) gnd (5) gnd (3) ZSCD5030 - common connected zsxd5030 - isolated 4 - 13 schematic diagrams
