TLE7279-2E V50

The TLE7279-2 is a monolithic integrated voltage regulator with early warning and reset dedicated for microcontroller supplies under harsh automotive environment conditions. Due to its ultra low quiescent current the TLE7279-2 is perfectly suited for applications permanently connected to battery. In addition the regulator can be shut down via the Enable input causing the current consumption to drop below 3 µA. The TLE7279-2 is equipped with an output current limitation and an over temperature shutdown protecting the device against overload, short circuit and over temperature. It operates in the wide junction temperature range from -40 °C 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.
