Description
The TLE42664 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 TLE4266-2. It is functional compatible to the TLE4266, but has a reduced
quiescent current of typ. 40µA. The TLE42664 is especially designed for applications requiring very low standby
currents, e.g. with a permanent connection to the car’s battery. It can be disabled/enabled by the integrated EN
pin. The device is available in the small surface mounted PG-SOT223-4 package and is pin compatible to the
TLE4266-2 and the TLE4266. 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 TLE42664 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. A logical “HIGH” at the ENABLE pin enables the device.

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.
