AP7387Q-33FDCW-7

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AP7387Q-33FDCW-7 is a fixed-output automotive-compliant ultra-low dropout (ULDO) linear regulator manufactured by Diodes Incorporated. It provides a nominal 3.3V output with a maximum continuous current of 150mA. The device supports an input voltage range from 5V to 60V and features a typical quiescent current of 2μA. It offers high power supply rejection ratio (PSRR) of 70dB at 1kHz and maintains output voltage accuracy within ±2%. The component operates over a junction temperature range of -40°C to +125°C and utilizes the U-DFN2020-6 (SWP) package.

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

Verify that the procurement channel is authorized to ensure compliance with IATF 16949 manufacturing standards. Confirm the part suffix matches the required U-DFN2020-6 package configuration. Validate that the component meets RoHS 3 and halogen-free specifications as defined by the manufacturer's quality definitions before finalizing orders.

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

Select this component when designing circuits requiring high input voltage tolerance up to 60V combined with low standby power consumption. Ensure the application demands a fixed 3.3V rail capable of sourcing 150mA. Verify that the PCB layout can accommodate the U-DFN2020-6 footprint and utilize adequate copper area for thermal dissipation given the exposed pad design.

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

This part belongs to the AP7387Q series, which is specifically engineered for automotive environments. Unlike standard industrial regulators, this series incorporates rigorous quality controls and PPAP capabilities. It shares core electrical characteristics with other variants in the family but is distinguished by its automotive certification and specific package options like the U-DFN2020-6.

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

Direct substitutes include other AP7387Q variants with different output voltages or packages, such as AP7387Q-30FDCW-7 or AP7387Q-36Y-13. Cross-referencing with non-automotive AP7387 series parts requires verification of operating temperature ranges and reliability standards.
