IRU1207-33CSTR

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

The IRU1207-33CSTR is a fixed-output synchronous buck switching regulator manufactured by Infineon Technologies. It integrates high-side and low-side power MOSFETs to deliver a constant 3.3V output voltage with a maximum load current of 7A. The device operates from an input supply range of 4.5V to 28V, utilizing a fixed internal switching frequency of 400kHz. Designed for surface-mount assembly, it is housed in a compact 16-lead TSSOP package (EP) rated for industrial operating temperatures between -40°C and +85°C.
