PG-TO263-5
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
PG-TO252-5
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.
Choosing External Components
The input capacitor CI is necessary for compensating line influences. The output capacitor CQ is necessary for the
stability of the regulating circuit. Stability is guaranteed at values specified in “Functional Range” on Page 8
within the whole operating temperature range.
