MILITARY DATA SHEET Original Creation Date: 09/07/95 Last Update Date: 12/10/96 Last Major Revision Date: 09/07/95 MNLM140LA-05-H REV 0B0 THREE TERMINAL POSITIVE REGULATORS General Description The LM140LA is an improved version of the LM78LXX series with a tighter output voltage tolerance, higher ripple rejection, better regulation and lower quiescent current. The LM140LA usually results in an effective output impedance improvement of two orders of magnitude, and lower quiescent current. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regulation. The voltages available allow the LM140LA to be used in logic systems, instrumentation, and other solid state electronic equipment. Although desinged primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. With adequate heat sinking the regulator can deliver 100mA output current. Current limiting is included to limit the peak output current to a safe value. Safe area protection for the output transistor is provided to limit internal power dissipation. If internal power dissipation becomes too high for the heat sinking provided, the thermal shut-down circuit takes over, preventing the IC from over-heating.
