AP7583AQ-FDZW-7

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

The AP7583AQ-FDZW-7 is a 300mA ultra-low dropout (ULDO) linear regulator from Diodes Incorporated, designed for automotive battery-powered applications. It features a wide input voltage range of 3V to 42V and delivers a fixed 5V output with ±1.5% accuracy. The device operates with a typical quiescent current of 3µA at no load and includes an integrated power-good indicator for supply monitoring. Packaged in a W-DFN2020-6 (SWP) Type A1 format, it supports operation across a junction temperature range of -40°C to +125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Includes a dedicated power-good pin that signals when the regulated output voltage exceeds a defined threshold, facilitating system sequencing and monitoring.
• Features low dropout voltage characteristics compatible with low equivalent series resistance ceramic capacitors for stable performance.
• Incorporates comprehensive protection mechanisms including thermal shutdown, short-circuit protection, and output current limiting.

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

• Powering microcontrollers (MCUs) and controller area network (CAN) transceivers
• Automotive head units
• EV and HEV battery management systems
• Body control modules

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

Verify the specific suffix FDZW corresponds to the W-DFN2020-6 package configuration required for your design. Confirm the 'A' designation indicates the inclusion of the Power-Good function, distinguishing it from the standard Q variant. Ensure component sourcing aligns with automotive quality standards such as AEC-Q100 qualification and IATF16949 manufacturing processes.

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

Select this component when a high-voltage input range up to 42V is required alongside a fixed 5V output. The integrated power-good feature makes it suitable for applications necessitating precise supply status monitoring. Consider the W-DFN2020-6 package for compact surface-mount designs requiring efficient thermal dissipation through the exposed pad.

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

This part belongs to the AP7583Q/AQ series of wide-input-voltage ULDO regulators manufactured by Diodes Incorporated. The series offers both adjustable and fixed output versions in multiple packages, including MSOP-8EP and TO252-4. The AP7583AQ variant specifically adds a power-good output compared to the base AP7583Q model.

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

AP7583Q-FDZW-7 serves as the functional equivalent without the power-good pin. AP7583AQ-MP-13 provides identical electrical specifications in an MSOP-8EP package. AP7583AQ-XXD4-13 offers the same functionality in a TO252-4 package.
