SNVS770I – JUNE 1999 – REVISED JANUARY 2015 LM2941x 1-A Low Dropout Adjustable Regulator
1 Features 3 Description The LM2941 positive voltage regulator features the
ability to source 1 A of output current with a typical
dropout voltage of 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 pin 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 Operating VIN Range: 6 V to 26 V
Output Voltage Adjustable From 5 V to 20 V
Dropout Voltage Typically 0.5 V at IOUT = 1 A
Output Current in Excess of 1 A
Trimmed Reference Voltage …
