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.
