Overview

Dimensioning Information on External Components

The input capacitor CI is recommended for compensation of line influences. The output capacitor CQ is 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 component also has a number of internal circuits for protection against:

• Overload

• Overtemperature

• Reverse polarity
