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.
