DESCRIPTION
The LM140L series of three terminal positive Connection Diagrams
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 Figure 1. TO Metal Can Package (NDT)
LM140LA usually results in an effective output (Bottom View)
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 Figure 2. TO-92 Plastic Package (LP)
obtain adjustable voltages and currents. (Bottom View)

(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
