Check for Samples: LM2940QML, LM2940QML-SP FEATURES DESCRIPTION The LM2940 positive voltage regulator features the
ability to source 1A of output current with a dropout
voltage of typically 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 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 30 mA. Higher
quiescent currents only exist when the regulator is in
the dropout mode (VIN -VOUT ≤ 3V). 1 2 Available with Radiation Ensure
