TLF1963 is a low dropout voltage regulator available in PG-TO263-5 and PG-TO252-5 SMD package. The IC regulates an input voltage V I in the range of 2.5 V < V I < 20 V to an adjustable output voltage of 1.21 V < V Q,nom < V I -V dr. The device is capable of supplying loads up to 1.5 A. The regulator can be enabled and disabled via the Enable input.The integrated output current limitation and the overtemperature shutdown will protect the device against failures like output short circuit to GND, overcurrent and overtemperature.
The TLF1963 provides the ideal solution for systems requiring several supply voltages. With its adjust feature the regulator can provide all supply voltages between 1.21 V and the available input voltage, which offers a high flexibility to the system designer.
