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

Verify the specific ordering suffix 'TRE1' confirms the Tape & Reel packing configuration and 'E1' indicates RoHS compliance as documented in the manufacturer's datasheet. Ensure the component matches the TO-252-5 package outline dimensions and marking ID requirements specified in the official documentation before finalizing procurement orders.

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

Select this component when designing systems that require a fixed 5.0V rail with high current capability and minimal voltage drop. The TO-252-5 package provides adequate thermal dissipation for continuous 1.5A operation. Consider the TTL/CMOS compatible enable pin if active power control is required for the application circuit design.

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

This part belongs to the AZ39151 series of 1.5A ultra low dropout linear regulators produced by Diodes Incorporated. The series includes fixed 3.3V and adjustable (ADJ) versions alongside the 5.0V variant. All models share identical electrical performance profiles and are housed in the same TO-252-5 package family.

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

Compatible substitutes within the same product line include AZ39151D5-3.3TRE1 for 3.3V applications and AZ39151D5-ADJTRE1 for adjustable voltage requirements. These parts maintain identical pinouts and electrical specifications while differing only in the regulated output voltage setting.

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

What is the function of Pin 5 on the AZ39151D5-5.0TRE1?

Pin 5 serves as No Connection (NC) for the fixed voltage versions of the AZ39151.

How does the enable pin operate on this regulator?

The enable pin is TTL/CMOS compatible; a logic high signal enables the regulator, while a logic low or open state shuts it down.
