LM2941/LM2941C
1A Low Dropout Adjustable Regulator
General Description
The LM2941 positive voltage regulator features the ability to
source 1A of output current with a typical dropout voltage of
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 pin current when
the differential between the input voltage and the output volt-
age exceeds approximately 3V. The quiescent current with
1A of output current and an input-output differential of 5V is
therefore only 30 mA. Higher quiescent currents only exist
when the regulator is in the dropout mode (VIN − VOUT ≤ 3V).
Designed also for vehicular applications, the LM2941 and all
regulated circuitry are protected from reverse battery instal-
lations or two-battery jumps. During line transients, such as
load dump when the input voltage can momentarily exceed
the specified maximum operating voltage, the regulator will
automatically shut down to protect both the internal circuits
and the load. Familiar regulator features such as short circuit
and thermal overload protection are also provided.
