LM2940QML
October 12, 2011
1A Low Dropout Regulator
General Description
The LM2940 positive voltage regulator features the ability to
source 1A of output current with a dropout voltage of typically
0.5V and a maximum of 1V over the entire temperature range.
Furthermore, a quiescent current reduction circuit has been
included which reduces the ground current when the differ-
ential between the input voltage and the output voltage ex-
ceeds approximately 3V. The quiescent current with 1A of
output current and an input-output differential of 5V is there-
fore only 30 mA. Higher quiescent currents only exist when
the regulator is in the dropout mode (V
IN VOUT ≤ 3V).
Designed also for vehicular applications, the LM2940 and all
regulated circuitry are protected from reverse battery instal-
lations or 2-battery jumps. During line transients, such as load
dump when the input voltage can momentarily exceed the
specified maximum operating voltage, the regulator will au-
tomatically shut down to protect both the internal circuits and
the load. The LM2940 cannot be harmed by temporary mirror-
image insertion. Familiar regulator features such as short
circuit and thermal overload protection are also provided.
