AZ1117H-3.3TRE1

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

The AZ1117H-3.3TRE1 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated, providing a stable 3.3V output with a maximum current of 1A. It operates within an input voltage range up to 15V and features a typical dropout voltage of 1.15V at full load. The device incorporates a trimmed bandgap reference ensuring ±1% output voltage accuracy. Integrated protection mechanisms include adjustable current limiting and thermal shutdown to safeguard against overload conditions. It is housed in a surface-mount SOT223 package and supports an operating junction temperature range from -40°C to +125°C.

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

Verify the component authenticity by checking for the specific marking ID EH16A on the SOT223 package. Confirm the RoHS compliance status as indicated by the TRE1 suffix. Ensure the supplier provides traceability documentation matching the manufacturer's specifications for the AZ1117 series.

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

Select this regulator when a fixed 3.3V supply is required with up to 1A load capability. The SOT223 package suits applications needing moderate heat dissipation without external heatsinks. Consider the 1.15V dropout characteristic for efficiency relative to input voltage headroom requirements.

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

This component belongs to the AZ1117 series of low dropout three-terminal regulators. The 'H' designation specifically identifies the SOT223 package variant. The '3.3' indicates the fixed output voltage level, while 'TRE1' denotes the tape and reel packaging format compliant with RoHS standards.

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

Diodes Incorporated recommends using the AZ1117C or AZ1117I series instead of the AZ1117H for new designs.
