IRU1010-18CD

IRU1010-18CD Description

The IRU1010-18CD from Infineon Technologies is a fixed-output linear voltage regulator designed to deliver a stable 1.8V output at 1A current. This surface-mount (DPAK) device operates within a wide input voltage range (up to 7V) and features a low dropout voltage of 1.3V at 1A, making it suitable for applications requiring efficient power conversion with minimal headroom. The regulator is obsolete but remains relevant for legacy designs due to its robust performance and reliability. It offers over-current and over-temperature protection, ensuring safe operation under demanding conditions. With a PSRR of 70dB (120Hz), it effectively filters noise, making it ideal for sensitive analog and digital circuits.

IRU1010-18CD Features

• Fixed 1.8V Output: Ensures precise voltage regulation for low-power ICs and microcontrollers.
• High Current Capability: Delivers 1A continuous current, supporting power-hungry components.
• Low Dropout Voltage: 1.3V @ 1A minimizes power dissipation, improving efficiency.
