TLE42994E V33

The TLE42994V33 is a monolithic integrated low dropout voltage regulator, especially designed for automotive applications that need to be in ON state during the car's engine is turned off. An input voltage up to 45 V is regulated to an output voltage of 3.3 V. The component is able to download up to 150 mA. It Is short-circuit, protected by the implemented current limitation and has an integrated over temperature shutdown. A reset signal is generated for an output voltage V Q,RT of typically 3.1 V. This threshold can be decreased by an external resistor divider The power-on reset delay time can be programmed by the external delay capacitor. The additional sense comparator provides an early warning function: Any voltage (e.g. the input voltage) can be monitored, an under voltage condition is indicated by setting the comparator's output to low. Additionally, an Enable function permitting enabling/disabling the regulator is also included. In case the regulator is disabled it consumes less current than 1 uA.

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.
