AZ1084CD-5.0TRG1

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

The AZ1084CD-5.0TRG1 is a fixed positive low-dropout linear regulator manufactured by Diodes Incorporated, delivering a nominal 5.0V output with a maximum load current of 5A. It operates within an input voltage range up to 12V and features a typical dropout voltage of 1.35V at full load. The device incorporates on-chip thermal limiting and current limiting circuits for protection against overload conditions. It utilizes a TO-252-2 surface-mount package and maintains operation across a junction temperature range from 0°C to +125°C.

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

Verify that the component matches the specific Diodes Incorporated datasheet DS36545 Rev. 5 - 2. Confirm the marking ID 'AZ1084CD-5.0G1' corresponds to the intended fixed 5.0V output version. Ensure the package variant aligns with the required TO-252-2 option (Option 1, 2, or 3) for PCB layout compatibility. Check for RoHS compliance status as defined by the manufacturer's green product definitions.

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

Select this regulator when a fixed 5.0V supply is required with high current capability up to 5A. Consider the thermal resistance characteristics and ensure adequate heatsinking or copper area on the PCB to manage power dissipation within the specified junction temperature limits. Verify that the input voltage remains within the recommended operating conditions to maintain regulation.

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

This component belongs to the AZ1084C series of 5A low dropout linear regulators. The series includes various fixed voltage options such as 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V, as well as an adjustable version. All variants share similar protection features and package options, differing primarily in their internal reference voltages and resistor networks.

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

Other part numbers within the AZ1084C family, such as AZ1084CD-3.3TRG1 or AZ1084CD-ADJTRG1, offer different fixed or adjustable output voltages but share the same package and protection features. Direct substitution requires verifying that the alternative voltage level meets the circuit requirements.
