AZ1117IH-5.0TRG1

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

The AZ1117IH-5.0TRG1 is a low dropout linear regulator from the AZ1117I series, designed for industrial temperature ranges (-40°C to +125°C). It provides a fixed 5.0V output with ±1% accuracy and supports up to 1A continuous load current. The device features a typical current limit of 1.35A, on-chip thermal shutdown, and a maximum quiescent current of 6mA. It operates with an input voltage up to 15V and utilizes SOT223 packaging.

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

Verify the specific suffix 'TRG1' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 'H' designation aligns with the intended industrial temperature grade specifications for your application environment. Ensure compatibility with RoHS 3 compliance standards if mandated by regional regulations.

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

Select this component when a stable 5V rail is needed under industrial thermal conditions. The 1.35A current limit offers headroom above the standard 1A rating. Verify that the system's input voltage remains within the 15V maximum limit while maintaining sufficient dropout voltage for regulation at peak loads.

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

This part belongs to the AZ1117I family, which distinguishes itself through optimized transient response and minimum input voltage performance. Unlike consumer-grade variants, the I-series is explicitly rated for the full -40°C to +125°C junction temperature range, making it suitable for demanding electronic environments.
