IFX54441LDV33XUMA1

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The IFX54441LDV33XUMA1 is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Infineon Technologies. It provides a stable 3.3V output with a maximum continuous current of 300mA. The device supports an input voltage range up to 20V and features a typical dropout voltage of 0.4V at full load. Key electrical specifications include a quiescent current of 60µA and a power supply rejection ratio (PSRR) of 65dB at 120Hz. It operates within a junction temperature range of -40°C to 125°C and is housed in an 8-DSO package with exposed pad.
