The stand-by regulator transforms an input voltage V I in the range of 5.6 V ≤ V I ≤ 42 V to an output voltage of V Q2 = 5.0 V ( ± 2%). The main output is tracked to the stand by output voltage and provides also 5 V. A versions of this device with 5 V/3.3 V and 5 V/2.6 V are also available, please refer to the data sheet TLE4473G V53/ TLE4473G V52. The Inhibit input INH1 disables the output Q1 only, whereas Inhibit input INH2 disables both, Q1 and Q2 output. The quiescent current then is 1 µA.
