Automotive Low Dropout Linear Voltage Regulator OPTIREG™ TLE42694-2EL
Application Circuit

The TLE42694-2 is a monolithic integrated low dropout voltage regulator, especially designed
for automotive applications. An input voltage up to 45 V (with reverse polarity protection) is
regulated to an output voltage of 5.0 V. The component is able to drive loads up to 150 mA.
Internal over-current and over-temperatuer features prevent damage of the part in over-load
conditions. A reset signal is generated for an output voltage VQ,rt of typically 4.65 V.
This threshold can be decreased by an external resistor divider. The power-on reset delay time
can be programmed by the external delay capacitor. The reset output is internally
connected to the output Q via a pull-up resistor.

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
