Description
The OPTIREG™ Linear TLE42694 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

the output Q via a pull-up resistor. If these integrated resistors are not desired, the TLE42794 can be used
instead of the TLE42694.
Dimensioning information on external components
The input capacitor CI is recommended for compensation of line influences. The output capacitor CQ is
necessary for the stability of the control loop.
Circuit description
The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and
drives the base of the series transistor via a buffer. Saturation control as a function of the load current prevents
any oversaturation of the power element. The TLE42694 also has a number of internal circuits for protection
against:
• Overload
• Overtemperature
• Reverse polarity
