Description
The TLE42644 is a monolithic integrated low dropout fixed voltage regulator for load currents up to 100 mA. It is
the 1-to-1 replacement product for the TLE4264-2. It is functional compatible to the TLE4264, but has a reduced
quiescent current of typ. 40µA. The TLE42644 is especially designed for applications requiring very low standby
currents, e.g. with a permanent connection to the car’s battery. The device is available in the small surface
mounted PG-SOT223-4 package and is pin compatible to the TLE4264-2 and the TLE4264. The device is
designed for the harsh environment of automotive applications. Therefore it is protected against overload, short
circuit and overtemperature conditions by the implemented output current limitation and the overtemperature
shutdown circuit. The TLE42644 can be also used in all other applications requiring a stabilized 5 V voltage.
An input voltage up to 45 V is regulated to VQ,nom = 5 V with a precision of ±3 %. An accuracy of ±2 % is kept for
load currents up to 50 mA.

Note: Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are
not designed for continuous repetitive operation.
