Voltage Regulator TLE 4284 Features • • • • • • • • • • Adjustable output voltage or 1.5V, 1.8V, 2.6V, 3.3 V, 5.0V output voltage 1.0 A output current Low dropout voltage, typ. 1 V Short circuit protection Overtemperature protection Wide operating range up to 40 V Wide temperature range of Tj = -40 to 150 °C Suitable for use in automotive electronics Green Product (RoHS compliant) AEC Qualified PG-TO-252-3 Functional Description The TLE 4284 is a monolithic integrated NPN type voltage regulator that can supply loads up to 1.0 A. The chip is housed in a surface mounted PG-TO252-3-11 package (DPAK). It is designed to supply microprocessor systems or other loads under the severe conditions of automotive applications and therefore it is equipped with additional protection against overload, short circuit and overtemperature. An input voltage VI in the range of (VQ + VDR) < VI < 40 V is regulated to VQ. The dropout voltage VDR ranges from 1.1 V to 1.4 V depending on the load current level. The device operates in the temperature range of Tj = -40 to 150 °C.
