AZ1084T-5.0E1

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

The AZ1084T-5.0E1 is a fixed-output positive low dropout linear regulator manufactured by Diodes Incorporated, providing a nominal 5.0V output at up to 5A load current. It operates within an input voltage range of up to 12V and features a maximum dropout voltage of 1.5V at full load. The device incorporates on-chip thermal limiting and current limiting circuits for protection against overload conditions. Packaged in a TO-220-3 through-hole format, it supports an operating junction temperature range from 0°C to +125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated thermal limiting protects the device against excessive junction temperatures caused by overload or high ambient conditions.
• Built-in current limiting circuit safeguards against short circuits and overcurrent scenarios.
• Fixed output version integrates internal adjustment resistors for simplified design implementation.

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

Verify the specific suffix E1 confirms lead-free compliance with RoHS directives before procurement. Confirm the package type matches the required TO-220-3 form factor for through-hole mounting. Ensure the fixed 5.0V output variant aligns with the target circuit requirements rather than adjustable versions.

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

Select this component when a stable 5V rail is required for loads up to 5A with minimal external components. The fixed output configuration eliminates the need for external feedback resistors found in adjustable variants. Consider the thermal resistance characteristics of the TO-220-3 package for adequate heat dissipation under heavy load conditions.

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

This part belongs to the AZ1084 series of 5A low dropout linear regulators offered by Diodes Incorporated. The series includes various fixed voltage options (1.5V, 1.8V, 2.5V, 3.3V) and an adjustable version. The T suffix specifically denotes the TO-220-3 package style, distinguishing it from surface mount options like TO-263 or TO-252.

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

Direct substitutes include other AZ1084T-5.0 variants from Diodes Incorporated such as the green molding compound version AZ1084T-5.0G1. Cross-brand equivalents like the LT1084CT-5 may be considered if pin compatibility and electrical specifications are verified against the official datasheet.

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

What is the maximum input voltage for the AZ1084T-5.0E1?

The recommended operating condition specifies a maximum input voltage of 12V.

Does the AZ1084T-5.0E1 require external resistors for voltage setting?

No, the fixed 5.0V version integrates the adjustment resistors internally, unlike the adjustable ADJ version which requires two external resistors.
