TLE4473G V55-2
The TLE4473 is a monolithic integrated voltage regulator with two low dropout outputs, a main output Q1 for loads up to 300 mA and a stand by output Q2 providing a maximum of 190 mA. The stand-by regulator transforms an input voltage V I in the range of 5.6 V ≤ V I ≤ 42 V to an output voltage of V Q2 = 5.0 V ( ± 2%). The main output is tracked to the stand by output voltage and provides also 5 V. A versions of this device with 5 V/3.3 V and 5 V/2.6 V are also available, please refer to the data sheet TLE4473G V53/ TLE4473G V52. The Inhibit input INH1 disables the output Q1 only, whereas Inhibit input INH2 disables both, Q1 and Q2 output. The quiescent current then is 1 µA.

| TLS810C1EJV33 BOARD | Linear Voltage Regulator | The 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=ff80808112ab681d0112ab69bfb202efTLS810C1EJV33 | on request |
| TLS810D1EJV50 BOARD | Linear Voltage Regulator | The 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.
