AZ1117CD-1.8TRG1

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

The AZ1117CD-1.8TRG1 is a fixed positive linear regulator from the AZ1117C series by Diodes Incorporated, housed in a TO-252-3 (DPak) surface-mount package. It provides a fixed 1.8V output with a maximum continuous current of 1A and a maximum input voltage of 15V. The device features a typical dropout voltage of 1.4V at 800mA and a power supply rejection ratio (PSRR) of 70dB at 120Hz. Quiescent current is specified at 6mA. Integrated protection includes thermal shutdown and current limiting. The operating junction temperature range extends from -20°C to 125°C.

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

Verify the specific suffix TRG1 confirms the tape-and-reel packaging format required for automated assembly processes. Ensure the component matches the TO-252-3 footprint dimensions on the target PCB layout. Confirm that the 1.8V fixed output aligns with the system design requirements, as adjustable or other voltage variants exist within the same series family.

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

Select this component when a fixed 1.8V rail is needed with 1A capacity in a compact surface-mount form factor. Consider the 1.4V dropout specification relative to the minimum input voltage available in the application. Evaluate the thermal management capabilities of the TO-252-3 package given the expected power dissipation and ambient operating temperatures.
