Description

The TLE4473GV52 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 TLE4473GV52). The device is also available with dual 5 V output voltage, please refer to the TLE4473GV52 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 TLE4473GV52 with both outputs disabled is < 1 A. The TLE4473GV52 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 TLE4473GV52 operates in the wide junction temperature range of -40 to 150 .
