TLE4473G V53

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 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 µ A. 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 over temperature.

TLS810C1EJV33 BOARDLinear Voltage RegulatorThe TLS810C1EJV33 is a linear voltage regulator of wide input voltage range, low drop out voltage and ultra low quiescent current. With an input voltage range of 2.75V to 42V and ultra low quiescent of only 8.5μA the regulators are perfectly suitable for automotive or any other supply systems connected permanently to the battery. The TLS810C1EJV33 is available in 3.3V output voltage version with an accuracy of 2 % and output current capability up to 100mA. It is stable with only a small ceramic capacitor of 1μF at the output. With extended operating range down to 2.75V, TLS810C1EJV33 is also suitable to supply automotive systems operating during cranking condition. TLS810C1EJV33 includes internal protection features like output current limitation and over-temperature shutdown. The output voltage is supervised by the Reset feature, including under-voltage reset and delayed reset release at power-on.Channel=ff80808112ab681d0112ab69bfb202efTLS810C1EJV33on request
TLS810D1EJV50 BOARDLinear Voltage RegulatorThe TLS810D1EJV50 is a linear voltage regulator featuring wide input voltage range, low drop out voltage and ultra low quiescent current. With an input voltage range of 2.75V to 42V and ultra low quiescent of only 9μA the regulators are perfectly suitable for automotive or any other supply systems connected permanently to the battery. The TLS810D1EJV50 is available in 5.0V output voltage version with an accuracy of 2 % and output current capability up to 100mA. It is stable with only a small ceramic capacitor of 1μF at the output. The device can be switched on and off by the Enable feature leading to a current consumption of less than 1μA. With extended operating range down to 2.75V, TLS810D1EJV50 is also suitable to supply automotive systems operating during cranking condition. TLS810D1EJV50 includes internal protection features like output current limitation and over-temperature shutdown.
