Description

The TLE42994G is a monolithic integrated low dropout voltage

regulator, especially designed for automotive applications that need to

be in ON state during the car’s engine is turned off. An input voltage up

to 45 V is regulated to an output voltage of 5.0 V. The component is

able to drive loads up to 150 mA. It is short-circuit protected by the

implemented current limitation and has an integrated overtemperature

shutdown. A reset signal is generated for an output voltage V

Q,rt

typically 4.65 V. This threshold can be decreased by an external

resistor divider. The power-on reset delay time can be programmed by

TLE42994 Overview 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 package) include additionally an Enable function permitting enabling/disabling the regulator. In case the regulator is disabled it consumes less current than 1 µA.

TLE42994 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.
