AP7583AQ-50D4-13

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

The AP7583AQ-50D4-13 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 provides a fixed 5.0V output with ±1.5% accuracy. The device includes an active-high enable pin and a power-good indicator for supply monitoring. It operates within a junction temperature range of -40°C to +125°C and is housed in a TO252-4 package.

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

• Integrated power-good indicator for system sequencing
• High input voltage tolerance up to 42V
• Robust protection including thermal shutdown and short-circuit current limit

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

• Powering microcontrollers (MCUs)
• Supplying CAN/LIN 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 ordering suffix D4 corresponds to the TO252-4 package configuration required for your design. Confirm that the AQ variant meets the need for the power-good signal compared to the standard Q version. Ensure compliance with AEC-Q100 qualification standards if the application demands automotive-grade reliability and PPAP capability.

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 TO252-4 package offers superior thermal dissipation compared to smaller surface-mount options, making it suitable for higher power dissipation scenarios. Consider the power-good feature if downstream sequencing or fault detection is necessary for the target application.

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

This part belongs to the AP7583Q/AQ series of wide-input-voltage ULDO regulators. The series distinguishes between the Q and AQ variants, where the AQ model adds a power-good function. The D4 suffix specifically denotes the TO252-4 package type, differentiating it from MSOP-8EP and W-DFN2020-6 alternatives within the same electrical family.

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

Direct substitutes include other AP7583AQ models with different packages such as AP7583AQ-MP-13 (MSOP-8EP) or AP7583AQ-FDZW-7 (W-DFN2020-6). For non-AQ versions without power-good, the AP7583Q-50D4-13 is electrically compatible except for the PG pin functionality.
