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

Verify component authenticity through authorized channels due to the presence of counterfeit risks in the market. Confirm that the received part matches the specific SOT-25 WR package marking and ordering suffix. Ensure compliance with RoHS 3 directives as specified in the manufacturer documentation before integration into final assemblies.

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

Select this component when a wide input voltage range up to 18 V is required alongside a fixed 5 V output. The SOT-25 package offers space-saving benefits compared to larger footprints. Consider the 300 mA current limit and thermal resistance characteristics for heat dissipation requirements in the target application environment.

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

This component belongs to the AP7370 series of ultra-low dropout regulators designed for portable electronics. The series includes various fixed output voltages and multiple package options such as SOT23, SOT89, and U-DFN2020-6. The AP7370-50WR-7 specifically denotes the 5.0 V version in the SOT-25 WR configuration.

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

The datasheet explicitly recommends using the AP7375 for new designs instead of the AP7370 series. Verify pinout compatibility and electrical specifications if substituting with other LDOs from different manufacturers or families.
