SNVS769J – MARCH 2000 – REVISED DECEMBER 2014 LM2940x 1-A Low Dropout Regulator
1 Features 3 Description The LM2940-N and LM2940C positive voltage
regulators feature the ability to source 1 A of output
current with a dropout voltage of typically 0.5 V and a
maximum of 1 V 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 3 V. The
quiescent current with 1 A of output current and an
input-output differential of 5 V is therefore only 30
mA. Higher quiescent currents only exist when the
regulator is in the dropout mode (VIN -VOUT ≤ 3 V). 1 Input Voltage Range = 6 V to 26 V
Dropout Voltage Typically 0.5 V at IOUT = 1 A
Output Current in Excess of 1 A
