AP7175SP-13

Overview

The AP7175SP-13 is a 3.0A ultra low-dropout linear regulator manufactured by Diodes Incorporated, housed in an SO-8EP package. It features an adjustable output voltage range from 0.8V to VIN minus dropout, with a typical dropout of 0.26V at 3A load and 25°C. The device utilizes separate VIN (1.2V to 3.65V) and VCNTL (3.0V to 5.5V) supply inputs for optimized performance. It includes an enable pin, power-good monitoring, internal soft-start, and thermal shutdown protection.

Feature Summary

• Dual supply architecture separates power input from control bias to minimize dropout voltage and reduce power dissipation.
• Integrated enable and power-good functions facilitate precise power sequencing for complex digital loads.
• Internal soft-start limits current surge during initialization to ensure stable heavy-load startup.
• Comprehensive protection mechanisms include thermal shutdown, current limiting, and short-circuit protection.

Applications

• Front Side Bus VTT generation
• Notebook and PC power management
• Server motherboard regulation
• Wireless communication equipment

Procurement Notes

Verify the component status before procurement as the datasheet explicitly states it is not recommended for new design with no alternate part provided. Confirm package integrity and lead-free compliance against RoHS standards. Ensure sourcing channels are authorized to avoid counterfeit risks associated with end-of-life components.

Selection Notes

Select this regulator when high continuous current capability near 3A is required with minimal voltage drop. The dual-supply design suits applications needing independent control logic voltage separation. Evaluate thermal requirements carefully due to the exposed pad dependency on PCB layout for adequate heat dissipation within the specified junction temperature limits.

Part Context

This component belongs to the AP7175 family of ultra low-dropout linear regulators produced by Diodes Incorporated. It is designed for high-current applications requiring tight regulation and fast transient response. The specific suffix indicates the SO-8EP package variant with tape and reel packaging configuration.

Replacement Considerations

The datasheet explicitly states there is no alternate part available for this component. Designers must verify if existing inventory suffices or if a redesign incorporating a different regulator family is necessary for new production runs.
