Description

The KA79XX/KA79XXA ser ies of three-terminal negative

regulators are available in TO-220 package and with

sever al fixe d out put vo ltages, maki ng them usefu l in a wide

range of applications. Each type employs internal current

limiting, thermal shutdown and safe operating area

protection, making it essentially indestructible.

Note:

(1) To specify an output voltage, substitute voltage value for "XX "

(2) Require d for stabilit y. F or va lue given, cap ac itor must be solid tanta l um. If alumini um ele ctr onics are us ed, at least ten times

value shown should be selected. CI is required if regulator is located an appreciable distance from power supply filter.

(3) To improve transient response. If large capacitors are used, a high current diode from input to output (1N400l or similar)

should be introduced to protect the device from momentary input short circuit.
