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

Verify the specific ordering suffix matches the required package type, as the AP7375Q series is available in multiple configurations including SOT89, SO-8EP, SOT25, and U-DFN2020-6. Confirm that the 'W5' designation corresponds to the intended SOT25 footprint for your PCB layout. Ensure compliance with RoHS and REACH directives if applicable to your manufacturing region.

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

Select this component when a high-voltage input range up to 45V is required alongside a stable 3.0V rail. The low quiescent current makes it suitable for battery-powered systems where standby consumption must be minimized. Verify that the thermal dissipation requirements are met within the operating temperature range of -40°C to +125°C, considering the package's thermal resistance characteristics.

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

This part belongs to the AP7375Q family of ULDO regulators designed for automotive environments. The series offers various fixed output voltages including 1.8V, 3.3V, and 5.0V. The 'Q' suffix indicates automotive qualification, while '30' specifies the 3.0V output version. The 'W5' code identifies the SOT25 surface-mount package variant.

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

Direct substitutes within the same family include AP7375Q-33W5-7 (3.3V output) or AP7375Q-18W5-7 (1.8V output), provided the voltage requirement differs. For non-automotive applications, the standard AP7375 series may be considered, though it lacks AEC-Q100 qualification.
