AZ1117CR2-5.0TRG1

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

The AZ1117CR2-5.0TRG1 is a fixed-output low dropout linear regulator from the AZ1117C series, manufactured by Diodes Incorporated. It provides a nominal 5.0V output with ±1% accuracy and supports up to 1A continuous load current. The device operates within an input voltage range of up to 15V and features a typical dropout voltage of 1.3V at 800mA in the SOT-89 package. Key electrical characteristics include a maximum quiescent current of 6mA, 70dB ripple rejection at 120Hz, and integrated thermal shutdown protection.

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

Verify the specific ordering suffix 'R2' corresponds to the required SOT-89 pinout option, as the datasheet distinguishes between multiple SOT-89 configurations. Confirm compliance with RoHS 3 and Halogen-free standards if environmental specifications are mandatory for the target assembly process.

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

Select this part when a stable 5.0V rail is needed for loads up to 1A with limited voltage headroom. Ensure the application utilizes low ESR ceramic output capacitors to maintain stability. Verify that the expected power dissipation remains within the thermal limits defined for the SOT-89 package without additional heatsinking.

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

This component belongs to the AZ1117C family of three-terminal regulators designed for efficiency in low-voltage environments. Unlike the standard AZ1117, the C-series emphasizes improved transient response and lower minimum input voltage requirements while maintaining robust current limiting capabilities.

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

Public confirmed substitute part numbers: AZ1117CH-5.0TRG1 (SOT-223 package), AZ1117CR-5.0TRG1 (Standard SOT-89 package). Verify pinout compatibility before substitution due to variations in SOT-89 options.
