Automotive Low Dropout Linear Voltage Regulator OPTIREG™ TLE4271-2G
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 OPTIREG™ Linear TLE4271-2 is functional and electrical identical to TLE4271.
The device is a 5-V low drop fixed voltage regulator. The maximum input voltage
is 42 V (65 V, ≤ 400 ms). Up to an input voltage of 26 V and for an output current up
to 550 mA it regulates the output voltage within a 2% accuracy. The short circuit
protection limits the output current of more than 650 mA. The IC can be switched
off via the inhibit input. An integrated watchdog monitors the connected controller.
The device incorporates overvoltage protection and temperature protection
that disables the circuit at overtemperature.
