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

Verify the specific ordering suffix 'SA' corresponds to the SOT23 package configuration before procurement. Confirm that the required output voltage matches the fixed 3.6V specification. Ensure the application environment remains within the recommended operating junction temperature range of -40°C to +125°C. Check for compliance with RoHS and halogen-free requirements if mandated by project specifications.

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

Select this component when a high-voltage input range up to 60V is required alongside low standby power consumption. It is suitable for designs needing fast transient response against rapid load changes. Consider the SOT23 package for space-constrained PCB layouts. Verify that the external capacitor values meet the stability requirements specified in the datasheet.

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

This part belongs to the AP7387 series of ultra-low dropout regulators designed for high-voltage applications. The series offers multiple fixed output voltages including 3.0V, 3.3V, 3.6V, and 5.0V. It is available in various packages such as SOT23, SOT25, SOT89, and U-DFN2020-6. An automotive-grade version, AP7387Q, is also available under a separate datasheet.

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

AP7387-33SA-7 provides a 3.3V output instead of 3.6V. AP7387-30SA-7 provides a 3.0V output. AP7387-50SA-7 provides a 5.0V output. All share the same SOT23 package and electrical characteristics except for the fixed output voltage.
