KA79MXX
3-Terminal 0.5A Negative
Voltage Regulator
Features
No external components required Output current in excess of 0.5A Internal thermal overload Internal short circuit current limiting Output transistor safe area compensation Output
voltages of -5V,-6V,-8V, -12V,-15V,-18V,-24V
Description
The KA79MXX series of 3-Terminal medium current negative
voltage regulators are monolithic integrated circuits designed as fixed
voltage regulators. These regulators employ internal current limiting, thermal shutdown and safe area compensation making them essentially indestructible.
