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 (VI − VO ≤ 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.
