Functional Description

The TLE 4473 is a monolithic integrated voltage regulator with two very low-drop

outputs, Q1 for loads up to 300 mA and Q2 providing a maximum of 180 mA. An input

voltage in the range of 5.6 V ≤ V_I≤ 45 V is transformed to V_Q2= 5.0 V (±2%) and

V_Q1= 3.3 V ±3% (TLE 4473 GV53) or V_Q1= 2.6 V ±3% (TLE 4473 GV52). The device is

also available with dual 5 V output voltage, please refer to the TLE 4473 GV55 data

sheet. Two inhibit pins allow a flexible power management. Both outputs can

independently be enabled or disabled. Thus the current consumption of the application

can be reduced to a minimum. The quiescent current of the TLE 4473 with both outputs

disabled is < 1 µA. The TLE 4473 is designed to supply microprocessor systems and

sensors under the severe conditions of automotive applications and is therefore

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.
