TLE4284DV50ATMA1 Infineon

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 PG-TO-252-3 Wide temperature range of T = -40 to 150 C j Suitable for use in automotive electronics Green Product (RoHS compliant) AEC Qualified 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 V in the range of (V + V ) < V < 40 V is regulated to V . The dropout I Q DR I Q voltage V ranges from 1.1 V to 1.4 V depending on the load current level. DR The device operates in the temperature range of T = -40 to 150 C. j Type Package Marking TLE 4284 DV PG-TO252-3-11 4284V TLE 4284 DV15 PG-TO252-3-11 4284V15 TLE 4284 DV18 PG-TO252-3-11 4284V18 TLE 4284 DV26 PG-TO252-3-11 4284V26 TLE 4284 DV33 PG-TO252-3-11 4284V33 TLE 4284 DV50 PG-TO252-3-11 4284V50 Data Sheet 1 Rev. 2.1, 2007-03-20 TLE 4284 Q I Control with Overtemperature Protection Internal Overcurrent Reference Protection GND AES02840 I Q Control with Overtemperature Adjust Protection Internal Overcurrent Reference Protection AES02839 Figure 1 Block Diagram for Fixed and Adjustable Output Voltage TLE 4284 Data Sheet 2 Rev. 2.1, 2007-03-20
