VOLTAGE REGULATOR, +15 VOLTS AT 0.5A
General Description
The LM140 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 0.5A 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.

Note 3:
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.
