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

Verify the specific suffix '13' corresponds to the 2500-unit tape and reel packaging configuration as defined in the manufacturer's ordering information. Confirm that the SOT89 package code matches the required PCB footprint dimensions. Ensure compliance with RoHS3 and halogen-free requirements if mandated by project specifications. Cross-reference the document revision DS44490 Rev. 8 to guarantee alignment with the latest electrical characteristics and marking information provided by Diodes Incorporated.

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

Select this component when a wide input voltage range up to 45V is required alongside a fixed 1.8V output. The integrated enable pin makes it suitable for systems requiring external power sequencing or standby modes. Verify that the 300mA load current capability meets the peak demand of the target circuit. Consider the SOT89 package for its thermal dissipation properties relative to smaller packages like SOT23. Ensure the application environment stays within the specified operating junction temperature range of -40°C to +125°C.

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

This part belongs to the AP7375 series of ultra-low dropout regulators designed for high-voltage input applications. The series offers multiple fixed output voltages including 1.8V, 3.0V, 3.3V, 3.6V, and 5.0V. It is available in various packages such as SOT23, SOT25, SOT89, and U-DFN2020-6. The family is characterized by fast transient response and low noise, making it distinct from standard LDOs limited to lower input voltages.
