TLE7273-2G V26

The TLE7273-2 is a monolithic voltage regulator with integrated window watchdog and reset dedicated for microcontroller supplies under harsh automotive environment conditions. Due to its ultra low quiescent current, the TLE7273-2 is perfectly suited for applications that are 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 TLE7273-2 is equipped with an output current limitation and an overtemperature 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.

The TLE 4266-2 is a monolithic integrated low-drop fixed voltage regulator which can supply loads up to 150 mA. It can be switched on and off by the INH pin. It is functional compatible to the TLE 4266, but with a reduced quiescent current of << 1 µ A in OFF mode and 40 µ A in ON mode. The TLE 4266-2 is especially designed for all applications that require very low quiescent current in ON and OFF mode. The device is available in the small surface mounted PG-SOT223-4 package. It is pin compatible to the TLE 4266 G. It is designed to supply microprocessor systems under the severe condition of automotive applications and therefore it is equipped with additional protection against over load, short circuit and overtemperature. Of course the TLE 4266-2 can be used in other applications, where a stabilized voltage and the inhibit feature is required. And input voltage VI up to 45 V is regulated to VQ = 5 V (TLE 4266-2 G) or VQ = 3.3 V (TLE 4266-2 GSV33) with an accuracy of ±3%. For the 5 V device an accuracy of ±2% is kept for a load current range  up to 50 mA. The device operates in the temperature range of T j = -40 to 150 °C. A high level at the

pin switches the regulator on.
