LM140L/LM340L Series
3-Terminal Positive Regulators
General 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 out-
put voltage tolerance (specified over the full military tem-
perature range), higher ripple rejection, better regulation and
lower quiescent current. The LM140LA regulators have
V
specification, 0.04%/V line regulation, and 0.01%/mA
OUT
load regulation. When used as a zener diode/resistor com-
bination 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 distribu-
tion 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 elec-
tronic equipment. Although designed primarily as fixed volt-
age 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-39 (H) and the LM340LA are also
available in the plastic TO-92 (Z). With adequate heat sink-
ing 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 pro-

vided 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.
