Description
The TLE4296-2 is a monolithic integrated low-drop voltage regulator in the very small SMD package
PG-SCT595. It is designed to supply e.g. microprocessor systems under the severe conditions of automotive
applications. Therefore the device is equipped with additional protection functions against overload, short circuit
and reverse polarity. At overtemperature the regulator is automatically turned off by the integrated thermal
protection circuit.
Input voltages up to 40 V are regulated to
V
Q,nom
= 3.3 V (V33 version) or 5.0 V (V50 version). The output is able
to drive a load of more than 30 mA while it regulates the output voltage within a 4% accuracy. To save energy the
device can be switched in stand-by mode via an inhibit input which causes the current consumption to drop below
5
μA.

Thermal Resistance
1) Not subject to production test, specified by design.
2) Internally limited
3) Worst case regarding peak temperature
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.
