3-terminal regulators output current up to 100 ma no external components internal thermal-overload protection internal short-circuit current limiting provided pb-free packages from the end of 2004 description this series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications. these applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. in addition, they can be used with power-pass elements to make high-current voltage regulators. one of these regulators can deliver up to 100 ma of output current. the internal limiting and thermal-shutdown features of these regulators make them essentially immune to overload. when used as a replacement for a zener diode-resistor combination, an effective improvement in output impedance can be obtained, together with lower bias current. electrical characteristics at specified virtual junction temperature, v i = otherwise noted) parameter test conditions t j 3 unit j min typ max i 1 ma to 40 ma 25 c output voltage v 7 v t i 1 a t 40 a full range v i o = 1 ma to 70 ma full range input v i = 25 c mv voltage regulation v i = 25 c mv ripple rejection v i = f = 120 hz 25 c db output i o = 1 ma to 100 ma 25 c mv voltage regulation i o = 1 ma to 40 ma 25 c mv output noise voltage f = 10 hz to 100 khz 25 c m v dropout voltage 25 c v bias current 25 c ma bias c rrent 125 c ma bias v i = full range 1.5 ma current change i o = 1 ma to 40 ma f ll range 0.1 ma 3 pulse-testing techniques maintain t j as close to t a as possible. thermal effects must be taken into account separately. all characteristics are measure d with a 0.33- m f capacitor across the input and a 0.1- m f capacitor across the output. full range for the 78l05 is t j = 0 c to 70 c wing shing computer components co., (h.k.)ltd. tel:(852)2341 9276 fax:(852)2797 8153 homepage: http://www.wingshing.com e-mail: wsccltd@hkstar.com
