IRU1117-25CP

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

The IRU1117-25CP is a low dropout, three-terminal fixed output positive regulator manufactured by Infineon Technologies. It provides a stable 2.5V output with a minimum current capability of 800mA. The device utilizes a TO-252 (DPAK) surface-mount package with two tabs for thermal dissipation. Designed for DC to DC conversion, it serves as a linear regulator suitable for powering low voltage integrated circuits in portable and PC-based systems.

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

Verify the suffix CP corresponds to the specific tape-and-reel or tube packaging variant required for your assembly line. Confirm the manufacturer datasheet revision matches your design specifications. Ensure the TO-252 package footprint aligns with your PCB layout guidelines. Check for RoHS compliance status if environmental regulations apply to your production region.

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

Select this component when a fixed 2.5V rail is required with up to 800mA load current. Consider the low dropout characteristic if input voltage margins are tight. Evaluate thermal performance in the TO-252 package based on ambient temperature and power dissipation requirements. Compare against adjustable variants if flexible voltage settings are needed instead of fixed outputs.
