IRU1050CM

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

The IRU1050CM is a positive adjustable linear regulator manufactured by Infineon Technologies, designed for high-current applications. It delivers a maximum output current of 4A with a typical dropout voltage of 1.2V at full load. The device supports an input voltage range up to 7V and provides an adjustable output voltage between 1.25V and 5.5V. Key electrical characteristics include a static current of 10mA and a power supply rejection ratio of 70dB at 120Hz. It features comprehensive protection mechanisms against overcurrent and thermal overload, operating reliably within a temperature range of 0°C to 125°C in a TO-263-5 surface-mount package.
