Product Brief TLF1963 Linear Post Regulator TLF1963 is a low dropout voltage regulator available in PG-TO263-5 and PG-TO252-5 SMD packages. The IC regulates an input voltage VI in the range of 2.5V < VI < 20V to an adjustable output voltage of 1.21V < VQ,nom < VI – Vdr. The device is capable to supply loads up to 1.5A. The regulator can be enabled and disabled via the Enable input. The integrated output current limitation and the over-temperature 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 1.21V and the available input voltage, this offers a high flexibility to the system designer.
