pj4800 series 700ma low dropout voltage regulators 1-6 2002/01.rev.a he series of fixed-voltage monolithic micr opower voltag e regulators is designed for a wide range of applications. t hes device excellent choice fo use in battery-power application. furthermore, the quiescent current increas es on slightly at dropout, which prolongs battery life. this series of fixed -voltage regul ators features very low quiescent current ( 100ma typ.) and very low drop output voltage (typ. 60mv al light load and 600mv at 700ma). 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 coe fficient. 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 accura cy within 2% at over timperature very low quiescent curr ent low dropout voltage (500mv typ) extremely tight load and line regulation very low temperatur e coe fficient unregulated dc input can withstand -20v reverse battery and +60v positive transients high-e ffi ciency linea r regulator battery powered systems portable instrumentation portable consumer equipment portable / palm top / notebook computers automotive electronics smps post-regulator device operating temperature packag e 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 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 a pplications ordering info rmation to-220-5l to-263-5l sot-223 / to-252 to-220 / to-263 p in : 1 . e r r o r 2. input 3. g r ound 4. output 5. shutdown a bsolute maximum ratings p in : 1. i n p u t 2. g r ound 3. outpu t
