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
voltage exceeds approximately 3V. The quiescent
current with 1A of output current and an input-output
differential of 5V is therefore only 30mA. Higher
quiescent currents only exist when the regulator is in
the dropout mode (V_I − V_O ≤ 3V).
Originally designed for vehicular applications, the
LM2941 and all regulated circuitry are protected from
reverse battery installations 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.
