TLE4278G Dettagli del prodotto

The TLE4278G is a monolithic integrated low-drop fixed output voltage regulator supplying loads up to 200 mA. The IC is available in a PG-DSO-14 package. It is designed to supply microprocessor systems under the severe conditions of automotive applications and therefore equipped with additional protection functions against over-load, short circuit and over temperature. The TLE4278G can also be used in other applications where a stabilized voltage is required.
