Automotive Low Dropout Linear Voltage Regulator OPTIREG™ TLE42694E
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 TLE42694E is a monolithic integrated low dropout voltage regulator,
especially designed for automotive applications. An input voltage up to 45 V is regulated to
an output voltage of 5.0 V. The component is able to drive loads up to 150 mA.
It is short-circuit proof by the implemented output current limitation and has an integrated
overtemperature shutdown. 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 additional sense comparator provides an early warning function: Any voltage
(e.g. the input voltage) can be monitored, an undervoltage condition is indicated
by setting the comparator’s output to low. The reset and sense output are internally
connected to Data Sheet 2 Rev. 1.41 2019-04-30 OPTIREG™ Linear TLE42694
5V low drop fixed voltage regulator the output Q via a pull-up resistor. If these integrated
resistors are not desired, the TLE42794 can be used instead of the TLE42694.
