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

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-

dissipation becomes too high for the heat sinking provided,

the thermal shut-down circuit takes over, preventing the IC

from overheating.
