IFX30081LDVGRNXUMA1

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

The IFX30081LDVGRNXUMA1 is a low-dropout (LDO) linear voltage regulator manufactured by Infineon Technologies. It features an adjustable output voltage and supports a maximum output current of 50 mA. The device operates with an input voltage range from 2.75 V to 42 V. Key electrical parameters include a typical quiescent current of 5 µA in active mode and 1 µA in standby mode. It offers high power supply rejection ratio (PSRR) performance, typically 60 dB at 100 Hz for the adjustable variant. The component is housed in an SOIC-8 surface-mount package and is rated for operation within a junction temperature range of -40°C to +125°C.

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

Verify the specific suffix 'GRN' against official Infineon documentation to confirm pinout and electrical characteristics, as suffixes often denote tape-and-reel packaging or specific temperature grades. Confirm availability status, as this part may be obsolete or subject to last-time buy restrictions. Ensure the selected package matches the PCB footprint requirements for SOIC-8 components.

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

Select this component when an adjustable output voltage is required alongside ultra-low quiescent current specifications. It is suitable for applications where input voltages vary significantly but remain within the 42 V maximum limit. Consider the thermal performance in the SOIC-8 package if high ambient temperatures are expected. Compare PSRR requirements against other LDO options if noise sensitivity is critical.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the IFX30081 family of low-dropout regulators designed for automotive and industrial environments. The family includes fixed and adjustable output variants with similar electrical profiles but different packaging options such as TSON and SOIC. These regulators are engineered to meet stringent reliability standards for harsh operating conditions.
