AP7165-SPG-13

Overview

The AP7165-SPG-13 is a 600mA adjustable output voltage, ultra-low dropout linear regulator manufactured by Diodes Incorporated. It operates within an input voltage range of 2.2V to 5.5V and provides an adjustable output voltage from 0.8V to 5.0V. The device features a typical quiescent current of 125µA and a very low dropout voltage of 300mV at a 500mA load. It includes built-in current limit and thermal shutdown circuitry for protection. The component is housed in an SO-8EP package and supports an ambient operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated Power-OK (POK) open-drain output for power sequence control
• Built-in current limiting and thermal shutdown protection against fault conditions
• Stable with any type of output capacitor equal to or greater than 4.7µF
• High power supply rejection ratio and fast transient response

Applications

• Servers and laptops
• Smart phones and PDAs
• MP3/MP4 players
• Bluetooth headsets
• FPGA and DSP core or I/O power

Procurement Notes

Verify the specific suffix '-13' corresponds to the SO-8EP package and tape-and-reel packaging configuration as defined in the manufacturer's ordering information. Confirm RoHS compliance status and lead-free finish requirements against the latest datasheet revision DS31270 Rev. 7. Ensure the application design accounts for the exposed pad thermal requirements associated with the SO-8EP package to maintain reliable operation within the specified junction temperature limits.

Selection Notes

Select this component when an adjustable LDO with integrated power sequencing indication is required for portable or battery-powered devices. The wide input voltage range and low quiescent current make it suitable for systems requiring efficient power management under varying load conditions. Consider the SO-8EP package for applications needing enhanced thermal dissipation capabilities compared to standard packages.

Part Context

The AP7165 belongs to Diodes Incorporated's family of low dropout regulators designed for low to medium power applications. It distinguishes itself through the inclusion of a Power-OK flag, facilitating complex power-up sequences in multi-rail systems. The device utilizes CMOS technology to achieve low quiescent current while maintaining high accuracy over line, load, and temperature variations.

Replacement Considerations

Consult the official Diodes Incorporated documentation for confirmed substitute part numbers. Verify pin compatibility and electrical specifications before substituting.
