AZ1117ID-1.2TRG1

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

The AZ1117ID-1.2TRG1 is a low dropout linear regulator from the AZ1117I series, manufactured by Diodes Incorporated. It provides a fixed 1.2V output with a maximum continuous current of 1A and features an industrial operating junction temperature range of -40°C to +125°C. The device utilizes a TO252-2 (DPAK) surface-mount package. Key electrical specifications include a typical dropout voltage of 1.3V at 800mA output current, a maximum quiescent current of 6mA, and a ripple rejection ratio of 70dB at 120Hz. Output voltage accuracy is maintained within ±1% across the specified temperature range.

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

Verify that the component matches the specific AZ1117I industrial grade designation rather than commercial variants. Confirm the package type corresponds to the TO252-2 form factor as indicated by the ID suffix. Ensure compliance with RoHS 3 and lead-free manufacturing standards required for the intended assembly process. Cross-reference the marking code AZ1117ID-1.2G1 to validate authenticity upon receipt.

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

Select this part when a fixed 1.2V rail is required in space-constrained designs utilizing the TO252-2 footprint. It is suitable for applications demanding robust thermal management and reliable performance across wide industrial temperature extremes. Consider the 1.3V dropout characteristic to ensure sufficient input-to-output voltage differential during peak load conditions.

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

This component belongs to the AZ1117I family of low dropout regulators designed for industrial environments. Unlike commercial counterparts, the I-series guarantees functionality over a -40°C to +125°C junction temperature range. The ID suffix specifically denotes the TO252-2 package variant, distinguishing it from SOT223 or other housing options within the broader product line.
