| MILITARY DATA SHEET MNLM140A-12-K REV 0B0 THREE TERMINAL POSITIVE REGULATORS General Description The LM140A monolithic 3-terminal positive voltage regulators employ internal current-limiting, thermal shutdown and safe-area compensation, making them essentially indestructible. If adequate heat sinking is provided, they can deliver over 1.0A output current. They are intended as fixed voltage regulators in a wide range of applications including local (on-card) regulation for elimination of noise and distribution problems associated with single-point regulation. In addition to use as fixed voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents. Considerable effort was expended to make the entire series of regulators easy to use and minimize the number of external components. It is not necessary to bypass the output, although this does improve transient response. Input bypassing is needed only if the regulator is located far from the filter capacitor of the power supply.

Operating Conditions are conditions under which the device functions but the specification might not be guaranteed. For guaranteed specifications and test conditions see the Electrical Characteristics. The maximum allowable power dissipation at any ambient temperature is a function of the maximum junction temperature for operation (TjMAX = 150 C), the junction-to-ambient thermal resistance (ThetaJA), and the ambient temperature (TA). PDMAX = (TjMAX - TA)/ThetaJA. If this dissipation is exceeded, the die temperature will rise above TjMAX and the electrical specifications do not apply. If the die temperature rises above 150 C, the device will do into thermal shutdown. The junction-to-ambient thermal resistance (ThetaJA) is 39 C/W. When using a heatsink, ThetaJA is the sum of the 4 C/W junction-to-case thermal resistance (ThetaJC) and the case-to-ambient thermal resistance (ThetaCA) of the heatsink. Human body model, 100pF discharged through 1.5K Ohms Note 2: Note 3: Recommended Operating Conditions (Note 1) Temperature Range (TA) (Note 2) -55 C to +125 C Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Conditions are conditions under which the device functions but the specification might not be guaranteed. For guaranteed specifications and test conditions see the Electrical Characteristics. The maximum allowable power dissipation at any ambient temperature is a function of the maximum junction temperature for operation (TjMAX = 150 C), the junction-to-ambient thermal resistance (ThetaJA), and the ambient temperature (TA). PDMAX = (TjMAX - TA)/ThetaJA. If this dissipation is exceeded, the die temperature will rise above TjMAX and the electrical specifications do not apply. If the die temperature rises above 150 C, the device will go into thermal shutdown. The junction-to-ambient thermal resistance (ThetaJA) is 39 C/W. When using a heatsink, ThetaJA is the sum of the 4 C/W junction-to-case thermal resistance (ThetaJC) and the case-to-ambient thermal resistance (ThetaCA) of the heatsink.
