SNVS758B –APRIL 1998–REVISED MARCH 2013

LM140L/LM340L Series 3-Terminal Positive Regulators

Check for Samples: LM140L, LM340L

FEATURES

The LM140LA/LM340LA are available in the low

•

Line Regulation of 0.04%/V

Load Regulation of 0.01%/mA

Output Voltage Tolerances of

profile metal three lead TO (NDT) and the LM340LA

are also available in the plastic TO-92 (LP). 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.

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 output voltage

tolerance (specified over the full military temperature

range), higher ripple rejection, better regulation and

lower quiescent current. The LM140LA regulators

have ±2% V_OUTspecification, 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 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.
