Automotive Low Dropout Linear Voltage Regulator OPTIREG™ TLE4296-2G V33
Application Circuit

The TLE4296-2G V33 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 VQ,nom = 3.3 V (V33 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.

Model performance :
- dynamic behavior not modeled (CQ/ESR stability, line/load transient
response, start-up, PSRR)
- static behavior is modelled by approximation to the real behavior of
the device at temperature = 25°C
