DESCRIPTION
The LM140L series of three terminal positive
regulators is available with several fixed output
voltages making them useful in a wide range of
applications. The LM140LA is an improved version of
the LM78LXX series with a tighter output voltage
tolerance (specified over the full military temperature
range), higher ripple rejection, better regulation and
lower quiescent current. The LM140LA regulators
have ±2% VOUT specification, 0.04%/V line regulation,
and 0.01%/mA load regulation. When used as a
zener diode/resistor combination replacement, 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, Hi-Fi,
and other solid state electronic equipment. Although
designed 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
100 mA 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 overheating.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
