THREE TERMINAL POSITIVE REGULATORS
General DescriptionThe LM140LA is an improved version of the LM78LXX series with a tighter output voltage
tolerance, 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 order 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, 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 100mA 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 over-heating.
