TLE4678EL

The TLE4678 is a monolithic integrated low dropout fixed output voltage regulator for loads up to 200 mA. An input voltage of up to 45 V is regulated to an output voltage of 5 V. The integrated reset and watchdog function, as well as several protection circuits, combined with a wide operating temperature range offered by the TLE4678 make it suitable for supplying microprocessor systems in automotive environments.The watchdog circuitry will be disabled in case the output current drops below a programmable threshold, enabling a microcontroller to switch in stand-by mode. Modifying the reset threshold is possible by an optional resistor divider. The TLE4678 is available in a PG-DSO-14 package which makes it pin-compatible to the TLE4278 as well as in a small thermally enhanced PG-SSOP-14 exposed pad package.

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.
