The LM140LA is an improved version of and ±4% over the Temperature Range the LM78LXX series with a tighter output voltage tolerance (specified over the full military temperature • Output Current of 100 mA range), higher ripple rejection, better regulation and • Internal Thermal Overload Protection lower quiescent current. The LM140LA regulators • Output Transistor Safe Area Protection have ±2% VOUT specification, 0.04%/V line regulation, and 0.01%/mA load regulation. When used as a • Internal Short Circuit Current Limit 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.
