1 GM79L00 series 100ma negative voltage regulator gm78l00 v2.04 www.gammamicro.com.tw typical application circuit description the GM79L00 series of fixed-voltage monolithic 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. each of these regulators can deliver up to 100ma of output current. the internal limiting and thermal shutdown features of these regulators make them essentially immune to overload. when used a s a replacement for a zener diodes-resistor combination, an effective improvement in output impedance can be obtained together with lower- bias current.. features ? maximum output current up 100ma ? fixed output voltage options: -5v, -6v, -8v, -9v, -12v, -15v, -18v and -24v ? no external components required ? internal thermal overload protection ? internal short circuit current limiting ? available in to-92, sot-89 and sop-8 packages v in gm79lxx v out c in 0.33
