DESCRIPTION
The LM2941 positive voltage regulator features the

quiescent current reduction circuit has been included
• Output Current in Excess of 1A
which reduces the ground pin current when the

voltage exceeds approximately 3V. The quiescent

≤ 3V).
• TTL, CMOS Compatible ON/OFF Switch
Designed also 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.
