EZ1581CMTRT

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

The EZ1581CMTRT is an adjustable positive Low Dropout (LDO) voltage regulator manufactured by Semtech. It operates within an input voltage range of 2.65 V to 7 V and provides an adjustable output voltage from 1.3 V to 5.7 V. The device supports a maximum output current of 0.8 A with a typical dropout voltage of 0.6 V at full load. Key electrical characteristics include a reference voltage of 1.25 V, line regulation of 0.035%, and load regulation of 0.2%. It features high power supply rejection ratio (PSRR) performance and is housed in a TO-263-5 (D2PAK-5) plastic package.

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

Verify the exact suffix 'T' indicates reel packaging configuration as per Semtech documentation. Confirm RoHS compliance status through official datasheets or manufacturer declarations before integration. Ensure the TO-263-5 footprint matches your PCB layout constraints. Cross-reference part numbers like EZ1581CM.TR for potential tape-and-reel variations. Validate lead-free soldering profiles against the component's thermal specifications.

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

Select this LDO when an adjustable output between 1.3 V and 5.7 V is required with up to 0.8 A current capacity. Consider its low dropout voltage for applications where input-output differential is minimal. Evaluate PSRR requirements; if higher rejection is needed, compare with other Semtech LDO families. Ensure the TO-263-5 package suits your thermal dissipation needs and assembly process. Verify compatibility with external feedback resistor networks for precise voltage setting.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The EZ1581CMTRT belongs to Semtech's EZ1581C series of adjustable positive LDO regulators. This family focuses on providing efficient, low-noise power solutions for portable and industrial applications. Similar parts in the series may offer fixed voltages or different current ratings. The CMTR designation typically denotes the specific package type and reel packaging format used for surface-mount assembly.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include EZ1581CM.TR which shares identical electrical specifications and pinout. Verify that any alternative LDO maintains the same 0.8 A output current and adjustable voltage range. Check for compatible TO-263-5 packages to ensure mechanical interchangeability. Confirm equivalent PSRR and dropout characteristics to maintain system performance stability.
