pj4800 series 400ma low dropout voltage regulators 1-6 2002/01.rev.a he series of fixed-voltage monolithic micropower voltage regulators is designed for a wide range of applications. thes device excellent choice fo use in battery-power application. furthermore, the quiescent current increases on slightly at dropout, which prolongs battery life. this series of fixed-voltage regulators features very low quiescent current ( 100ma typ.) and very low drop output voltage (typ. 60mv al light load and 600mv at 400ma). this includes a tight initial tolerance of 0.5% typ., extremely good load and line regulation of 0.05% typ., and very low output temperature coefficient. this series is offered in 3-pin to-263, to-220, to-252 & sot-223 package, and in 5-pin to-220 & to-263 package with shutdown input. ______________________________________________________________ ______________________________________ ? output accuracy within 2% at over timperature ? very low quiescent current ? low dropout voltage (400mv typ) ? extremely tight load and line regulation ? very low temperature coefficient ? unregulated dc input can withstand -20v reverse battery and +60v positive transients ? avaiable output voltage 5v, 3.3v, 2.5v, 1.8v ? high-efficiency linear regulator ? battery powered systems ? portable instrumentation ? portable consumer equipment ? portable / palm top / notebook computers ? automotive electronics ? smps post-regulator device operating temperature package pj48xxcz-5l to-220-5l pj48xxcm-5l to-263-5l pj48xxcz to-220 pj48xxcm to-263 pj48xxcp to-252 pj48xxcw -20 to +85 sot-223 xx- output voltage power dissipation internally limited lead temperature (soldering, 5 seconds) 260 storage temperature range .-65 to +150 operating junction temperature range -55 to +150 input supply voltage -20 to +35v continuous total dissipation at 25 free-air temperature to-220/to-263 to-252 sot-223 2w 1w 0.8w t features applications ordering information to-220-5l to-263-5l sot-223 / to-252 to-220 / to-263 pin 1. error 2. input 3. ground 4. output 5. shutdown absolute maximum ratings pin 1. input 2. ground 3. output
