EZ1581CT

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

The EZ1581CT is a high-performance positive voltage regulator from the EZ158X family, designed for applications requiring very low dropout voltage at up to 7 amps. It features dual input capability and remote sense operation to compensate for resistive losses. The device offers fast transient response and excellent regulation over line, load, and temperature variations. Packaged in a TO-263 format, it reduces heat dissipation compared to regular LDOs, allowing for heatsink size reduction or elimination.

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

Verify the specific suffix against official Semtech documentation to confirm package type and electrical tolerances. Ensure the ordering code matches the required current rating and dropout specifications for your design. Confirm RoHS compliance status through the manufacturer's datasheet before finalizing procurement.

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

Select this component when dual input voltage rails are available to maximize efficiency and minimize thermal output. The remote sense feature is critical for designs where significant voltage drop occurs across PCB traces or connectors. Evaluate thermal requirements to determine if heatsink reduction is feasible compared to standard LDO alternatives.
