Description
The IFX4949 is a monolithic integrated 5V voltage regulator with a very
low dropout output and additional functions as undervoltage reset with
power-on reset delay and input voltage sense. It is designed to supply
microcontroller controlled systems in all kinds of applications.
The IFX4949 is not to be used in automotive applications. For automotive
applications please refer to the Infineon TLF4949 voltage regulator
series.

Note: Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are
not designed for continuous repetitive operation.
