Automotive Low Dropout Linear Voltage Regulator TLE4263GM
Application Circuit

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

The maximum output current is more than 200 mA. The IC is short-circuit proof and incorporates
temperature protection which turns off the IC at overtemperature. The IC regulates an input
voltage VI in the range of 6 V < V I < 45 V to V Q,nom = 5.0 V. A reset signal is generated for an
output voltage of V Q,rt < 4.5 V. This voltage threshold can be decreased to 3.5 V by external
connection of a voltage divider. The reset delay can be set externally by a capacitor.
The integrated watchdog logic supervises the connected microcontroller. The IC can be switched
off via the inhibit input, which causes the current consumption to drop from 900 μA to typical 0 μA.
