Functional Description

TLF1963 is a low dropout voltage regulator available in PG-TO263-5 and

PG-TO252-5 SMD package. The IC regulates an input voltage VI

in the

range of 2.5 V < VI

< 20 V to an adjustable output voltage of

1.21 V < VQ,nom < VI

-Vdr. The device is capable to supply 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, this offers a high flexibility

to the system designer.
