AZ2940D-1.8TRG1

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

The AZ2940D-1.8TRG1 is a fixed-output ultra-low dropout linear regulator manufactured by Diodes Incorporated, providing a stable 1.8V output with a maximum current capacity of 1A. It operates within an input voltage range up to 6V and maintains performance across a junction temperature range of -40°C to +125°C. The device features a typical dropout voltage of 300mV at full load and incorporates comprehensive protection mechanisms including thermal shutdown and current limiting. Packaged in a compact TO-252-2 surface-mount format, it is designed for efficient power management in space-constrained applications.

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

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status and check for recent Product Change Notifications (PCN) regarding manufacturing site changes. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering to prevent package damage during assembly processes.

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

Select this regulator when a fixed 1.8V rail is required with high efficiency and minimal quiescent current. Compare dropout performance against alternative LDOs if input voltage margins are tight. Consider the TO-252-2 package thermal dissipation capabilities relative to the expected load current and ambient operating environment to ensure reliable long-term operation without overheating.

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

This component belongs to the AZ2940 series of ultra-low dropout linear regulators from Diodes Incorporated. The series offers various fixed output voltages tailored for different digital logic families. The AZ2940D variant specifically targets applications demanding high current capability combined with low noise and fast transient response, distinguishing it from standard LDOs in the same product family.

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

Direct substitutes include other 1.8V 1A LDOs in TO-252 packages such as the AP2121 series, though pinout and electrical specifications must be verified. Cross-reference with AZ2940D-3.3 variants only if voltage adjustment is acceptable. Ensure replacement parts match the original thermal resistance and protection feature set.
