EZ1582CM-2.5TRT

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

The EZ1582CM-2.5TRT is a dual-input low dropout linear regulator from the Semtech EZ158X family, designed for high-performance positive voltage regulation. It delivers up to 7A output current with a typical dropout voltage of 540mV in dual supply mode. The device features remote sense operation to compensate for resistive losses and provides excellent line and load regulation over variations in temperature and input conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix TRT against official Semtech documentation to confirm tape-and-reel packaging and pinout configuration. Ensure the component matches the EZ158X family specifications for dual-input operation and 7A current rating. Cross-reference the manufacturer part number to avoid confusion with single-input variants or different output voltage options within the same series.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this regulator when applications require very low dropout voltage at high currents, specifically where both 5V and 3.3V supplies are available on the motherboard. The dual-input design reduces heat dissipation, allowing for smaller heatsink sizes or elimination. It is suitable for systems demanding fast transient response and precise regulation under varying line, load, and temperature conditions.
