EZ1580CM-2.5TRT

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

The EZ1580CM-2.5TRT is a dual-input low dropout linear regulator manufactured by Semtech Corporation, designed for high-current applications requiring up to 7A output. It features a fixed 2.5V output voltage with a maximum dropout voltage of 0.8V and a typical value of 0.7V. The device supports a differential input voltage range from 2.5V to 12V and utilizes a TO-263 (D2PAK) package with five pins. Key electrical specifications include a line regulation of 0.064%/V and a load regulation of 0.4%. This component is engineered to minimize heat dissipation in systems utilizing both 5V and 3.3V supplies.
