TLE4471G

The TLE4471 is a monolithic integrated very low-drop triple voltage regulator. The main output supplies loads up to 450 mA and the additional tracked outputs can provide up to 50 mA and 100 mA. In addition the device includes a watchdog for microcontroller supervision, an under voltage reset, a power on reset and extended enabling features.The watchdog and reset timing can be chosen independently of each other. The TLE4471 is available in a Power PG-DSO-20 package. It is designed to supply microprocessor systems under the severe condition of automotive applications and therefore it is equipped with additional protection against overload, short circuit and over temperature. Of course the TLE4471 can be used in other applications as well. The TLE4471 operates in the temperature range of T j = -40 to 150° C.

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.
