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 VI 45 V is transformed to VQ2 = 5.0 V ( 2%) and  
VQ1 = 3.3 V 3% (TLE 4473 GV53) or VQ1 = 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.
