TLE42994V33 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.

TLE42994V33 Block Description and Electrical Characteristics 5 Block Description and Electrical Characteristics 5.1 Voltage Regulator The output voltage VQ is controlled by comparing a portion of it to an internal reference and driving a PNP pass transistor accordingly. The control loop stability depends on the output capacitor CQ, the load current, the chip temperature and the poles/zeros introduced by the integrated circuit.

TLE42994V33 Block Description and Electrical Characteristics Reset Reaction Time: The reset reaction time avoids that short undervoltage spikes trigger an unwanted reset “low” signal. The reset reaction rime trr considers the internal reaction time trr,int and the discharge time trr,d defined by the external delay capacitor CD (see typical performance graph for details).
