Circuit Description
The control amplifier compares a reference voltage, which is kept highly accurate by
resistance adjustment, to a voltage that is proportional to the output voltage and drives
the base of a series transistor via a buffer. Saturation control as a function of the load
current prevents any over-saturation of the power element.
The IC also incorporates a number of internal circuits for protection against:
•
•
•
•
Application Description
The IC regulates an input voltage in the range of 5.5 V <
to 26 V it produces a regulated output current of more than 650 mA. Above 26 V the
save-operating-area protection allows operation up to 36 V with a regulated output
current of more than 300 mA. Overvoltage protection limits operation at 42 V. The
overvoltage protection hysteresis restores operation if the input voltage has dropped
below 36 V. A reset signal is generated for an output voltage of
power-on reset can be set externally with a capacitor.
