3 / 36 page  TLE42994 Overview Data Sheet 3 Rev. 1.2, 2014-07-03 resistor divider. The power-on reset delay time can be programmed by the external delay capacitor. The additional sense comparator provides an early warning function: Any voltage (e.g. the input voltage) can be monitored, an under-voltage condition is indicated by setting the comparator’s output to low. The TLE42994GM (PG-DSO-14 package) and TLE42994E (PG-SSOP-14 exposed pad package) include additionally an Enable function permitting enabling/disabling the regulator. In case the regulator is disabled it consumes less current than 1 µA. Dimensioning Information on External Components The input capacitor C I 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 |
