Functional Description

The TLE 4473 is a monolithic integrated voltage regulator with two low dropout outputs,

a main output Q1 for loads up to 300 mA and a stand by output Q2 providing a maximum

of 190 mA. The stand-by regulator transforms an input voltage V_Iin 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 TLE 4473 G V53/

TLE 4473 G 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.

The TLE 4473 is designed to supply microprocessor systems and sensors under the

severe conditions of automotive applications and therefore is equipped with additional

protection functions against overload, short circuit and overtemperature. The device

operates in the wide junction temperature range of -40 °C to 150 °C.
