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 the series transistor via a buffer. Saturation control as a function of the load
current prevents any over-saturation of the power element. If the output voltage goes
below 96% of its typical value, an external capacitor is discharged on pin 4 by the reset
generator. If the voltage on the capacitor reaches the lower threshold
V
ST
, a reset signal
is issued on pin 2 and not cancelled again until the upper threshold
V
DT
is exceeded. For
an output current of less than
I
QN Off
= 10 mA the standby changeover turns off the reset
generator. The latter is turned on again when the output current increases, the output
voltage drops below 4.2 V or the delay capacitor is discharged by external measures.
The IC also incorporates a number of internal circuits for protection against:
