IRU1117-33CD

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

The IRU1117-33CD is a low dropout linear regulator from the Infineon Technologies portfolio, designed to provide a stable 3.3V output with a maximum load current of 0.8A. It operates within an input voltage range of 4.5V to 15V and features a typical dropout voltage of 1.2V at full load. The device ensures high power supply rejection ratio (PSRR) of 65dB and maintains line regulation at 6mV and load regulation at 10mV. It functions reliably across a temperature range of 0°C to +125°C and is housed in a SOT-223-4 surface-mount package.
