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 (VIN − VOUT ≤ 3V).
