Functional Description
TLE42344G is a 5 V low dropout fixed voltage regulator in an PG-SOT223-4 package. The IC regulates an input
voltage
IC is protected against shortcircuit and overheat by the integrated output current limitation and the
overtemperature shutdown
Dimensioning Information on External Components
The input capacitor
stability of the regulating circuit. Stability is guaranteed at values
operating temperature range.
Circuit Description
The control amplifier compares a reference voltage, which is kept highly precise by resistance adjustment, to a
voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation
control, working as a function of load current, prevents any over-saturation of the power element.
