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.
The LM140LA/LM340LA are available in the low
profile metal three lead TO (NDT) and the LM340LA
are also available in the plastic TO-92 (LP). 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.
For applications requiring other voltages, see LM117L
Data Sheet.

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.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits.
(2) A military RETS specification is available upon request. At the time of printing, the LM140LA-5.0, -12, and -15 RETS specifications
complied with the Min and Max limits in this table. The LM140LAH-5.0, LM140LAH-12, and LM140LAH-15 may also be procured as
Standard Military Drawings.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(4) Thermal resistance of NDT-package is typically 26°C/W θjC, 250°C/W θjA still air, and 94°C/W θjA 400 lf/min of air. For the LP-package is
60°C/W θjC, 232°C/W θjA still air, and 88°C/W θjA at 400 lf/min of air. The maximum junction temperature shall not exceed 125°C on
electrical parameters.
