Qualified for automotive applications. Product validation according to AEC-Q100/101. 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 V of typically 4.65 V. This threshold can be decreased by an external resistor divider. The power-on reset Q,rt 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 comparators output to low. The reset and sense output are internally connected to Data Sheet 1 Rev. 1.41 www.infineon.com/OPTIREG-Linear 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. Dimensioning information on external components The input capacitor C is recommended for compensation of line influences. The output capacitor C is I Q 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 Type Package Marking TLE42694G PG-DSO-8 42694G TLE42694GM PG-DSO-14 42694GM TLE42694E PG-SSOP-14 exposed pad 42694E Data Sheet 2 Rev. 1.41 2019-04-30
