Functional Description
The TLE 4296 G is a monolithic integrated low drop voltage regulator in the very small
SMD package P-SCT595-5. 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
= 3.0 V (V30 version) 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.
