1A, 26V, High PSRR, Low Dropout Voltage Regulator - 

The LM2940T-10.0/NOPB positive voltage regulator featuring the ability to source 1A of output current with a dropout voltage of typically 05 V 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 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).
