AZ1117H-1.8TRG1

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

The AZ1117H-1.8TRG1 is a positive fixed-output linear regulator from the AZ1117 series, manufactured by Diodes Incorporated (originally BCD Semiconductor). It provides a nominal output voltage of 1.8V with a maximum continuous output current of 1A. The device operates within an input voltage range up to 15V and features a typical dropout voltage of 1.15V at full load. It incorporates a trimmed bandgap reference ensuring 1% output voltage accuracy. Key electrical specifications include a quiescent current of 5mA to 10mA and a ripple rejection ratio of 75dB at 120Hz. The component supports an operating junction temperature range of -40°C to +125°C.

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

Verify that the ordering suffix 'TRG1' corresponds to the tape and reel packaging format and green compliant status as defined in the manufacturer's official ordering information table. Confirm the package designation 'H' matches the SOT-223 physical dimensions required for the target PCB footprint. Ensure the specific part number aligns with the 1.8V fixed output variant rather than adjustable or other voltage versions.

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

Select this component when a stable 1.8V rail is required with up to 1A load capacity. The low dropout characteristic allows operation with minimal input-to-output voltage differential. Verify that the application environment stays within the specified -40°C to +125°C junction temperature range. Consider the thermal resistance of the SOT-223 package for heat dissipation calculations under maximum load conditions.
