( ww w . e c m o s . c o m . t w ) p a g e 1 o f 15 4d01 n - rev.p00 2 500ma positive voltage regulators typical application circuit pin configuration general description ec 78 xx m series of three - terminal positive voltage regulators employ built - in current limiting, thermal shutdown, and safe - operating area protection which makes them virtually immune to damage from output overloads. with adequate heat si nk, they can deliver in excess of 0.5a output current. typical applications would include local (on - card) regulators which can eliminate the noise and degraded performance associated with single - point regulation. features ? maximum output current up 500ma ? fixed output voltage options: 5v, 6v, 8v, 9v, 10v, 12v, 15v, 18v and 24v ? no external components required ? internal thermal overload protection ? internal short circuit current limiting ? available in to - 252, to220 and to263 packages
