IFX1963TEV数据手册Infineon中文资料规格书

描述 Description

The IFX1963 is a low dropout voltage regulator available in PG-TO252-5 SMD package. The IC regulates an input voltage VIN in the range of 2.5 V < VIN < 20 V to an adjustable output voltage of 1.21 V < VQOUT,nom < VIN -VdrDR. 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 IFX1963 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.
