LM79XX
LINEAR INTEGRATED CIRCUIT
3 TERMINAL 1A NEGATIVE
VOLTAGE REGULATOR
DESCRIPTION
The UTC LM79XX series of three-terminal negative regulators is
available several fixed output voltage, making them useful in a wide
range of application. Each type employs internal current limiting, thermal
shut-down and safe area protection, making it essentially indestructible.
FEATURES
* Output Current Up to 1A
*-5V, -6V, -8V, -9V,-12V, -15V, -18V, -24V Output Voltage Available
* Thermal Overload Protection
* Short Circuit Protection
