IFX54441EJVXUMA1

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

The IFX54441EJVXUMA1 is a linear voltage regulator IC from Infineon Technologies, featuring a positive adjustable output with a maximum current capability of 300mA. It operates within a wide input voltage range up to 20V and delivers a fixed 5V output in the specific EJV50 variant context, housed in an 8-DSO package with a bare pad. Key electrical parameters include a quiescent current of 30µA, a dropout voltage of 0.41V at 300mA, and a Power Supply Rejection Ratio (PSRR) of 65dB at 120Hz. The device supports operation across a temperature range of -40°C to 125°C and includes protection features such as overcurrent, thermal shutdown, and reverse polarity protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm the specific suffix indicates the correct package and output configuration. Check for obsolescence status as some variants may be discontinued. Ensure compliance with RoHS3 specifications if required by your manufacturing standards. Validate lead times and availability directly with suppliers due to potential supply chain variations.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a low-noise, high-reliability LDO is required for sensitive analog or digital loads. The 300mA output current suits moderate power applications. Consider the 8-DSO package for surface-mount assembly constraints. Evaluate the 20V input range against your system's supply voltage. Compare quiescent current requirements against other family members if ultra-low power is critical.
