Description
The TLE42754 is a monolithic integrated low-dropout voltage
regulator in a 5-pin TO-package, especially designed for automotive
applications. An input voltage up to 42 V is regulated to an output
voltage of 5.0 V. The component is able to drive loads up to
450 mA. It is short-circuit proof by the implemented current limitation
and has an integrated overtemperature shutdown. A reset signal is
generated for an output voltage V_Q,rt of typically 4.65 V. The power-on
reset delay time can be programmed by the external delay capacitor.
Dimensioning Information on External Components
An input capacitor C_I is recommended for compensation of line
influences. An output capacitor C_Q is necessary for the stability of the
control loop.
