National P/N LM2984C - Microprocessor Power Supply System
The LM2984C positive voltage regulator features three independent and tracking outputs capable of
delivering the power for logic circuits, peripheral sensors and standby memory in a typical microprocessor
system. The LM2984C includes circuitry which monitors both its own high-current output and also an
external P. If any error conditions are sensed in either, a reset error flag is set and maintained until the
malfunction terminates. Since these functions are included in the same package with the three regulators, a
great saving in board space can be realized in the typical microprocessor system. The LM2984C also features
very low dropout voltages on each of its three regulator outputs (0.6V at the rated output current).
Furthermore, the quiescent current can be reduced to 1 mA in the standby mode.
Designed also for vehicular applications, the LM2984C and all regulated circuitry are protected from reverse
battery installations or 2-battery jumps. Familiar regulator features such as short circuit and thermal
overload protection are also provided. Fixed outputs of 5V are available in the plastic TO-220 power package.
