AZ2940T-3.3E1

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

The AZ2940T-3.3E1 is a low-dropout linear voltage regulator manufactured by Diodes Incorporated, belonging to the AZ2940 series. It provides a fixed 3.3V output with a maximum continuous current of 1A. The device features an ultra-low dropout voltage of 280mV at full load and includes internal protection mechanisms such as thermal shutdown and current limiting. It is housed in a TO-252-2 surface-mount package and operates within a junction temperature range of -40°C to 125°C.

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for End-of-Life notifications as discontinuance may affect long-term availability and supply chain stability.

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

Select this component when a stable 3.3V rail is required from higher input voltages with minimal heat generation. Ensure input voltage exceeds the minimum dropout threshold plus 3.3V. Verify that the expected load current remains within the 1A limit and that PCB thermal design accommodates the dissipation in the TO-252-2 package.

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

This part is part of the AZ2940 family of 1A LDO regulators from Diodes Incorporated. It shares functional similarities with other fixed-output variants in the series but differs in specific output voltage settings. The TO-252-2 package allows for efficient heat dissipation compared to smaller SOT packages, making it suitable for moderate power applications.

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

Direct pin-compatible substitutes include other 1A LDOs with 3.3V fixed output and similar dropout characteristics. Verify package compatibility (TO-252-2) and electrical parameters such as quiescent current and PSRR before substitution.
