LM2984C LM2984C Microprocessor Power Supply System Literature Number: SNVS768 LM2984C Microprocessor Power Supply System
General Description
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 mP. 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. Features
