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

Verify the component matches the specific TO220-3 through-hole package configuration required for your assembly process. Confirm that the RoHS compliance status aligns with environmental regulations applicable to your region. Ensure the ordering suffix E1 corresponds to the lead-free specification intended for your manufacturing line.

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

Select this part when a stable 5V rail is needed for loads up to 1A with moderate heat dissipation capabilities. The TO220-3 package facilitates mounting on heatsinks for high-power applications. Consider the 1.15V dropout requirement to ensure sufficient headroom between input and output voltages under all operating conditions.

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

This component belongs to the AZ1117 series of low dropout linear regulators. The series offers various fixed voltage options and adjustable versions across multiple packages including SOT223, SOT89, and TO263. The T suffix specifically denotes the TO220-3 package variant designed for higher power handling compared to surface-mount alternatives.

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

The datasheet explicitly states that this product is not recommended for new design and advises using AZ1117C or AZ1117I instead. These newer variants likely offer updated specifications or packaging improvements while maintaining functional compatibility.
