AP7115-15SEG-7

Overview

The AP7115-15SEG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated, providing a stable 1.5V output with a maximum current of 150mA. It operates within an input voltage range of 2.5V to 5.5V and features a typical quiescent current of 50µA. The device incorporates comprehensive protection mechanisms including current limit, short circuit protection, and thermal shutdown. Packaged in the SOT353 form factor, it ensures high power supply rejection ratio and fast transient response suitable for battery-powered applications.

Feature Summary

• Integrated shutdown control via EN pin for power management
• Built-in current limit and thermal shutdown protection
• Low dropout voltage operation at full load capacity
• High power supply rejection ratio for noise reduction

Applications

• Wireless communication devices
• GSM/GPRS cellular phones
• Handheld mobile devices
• Battery powered portable electronics

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance and green molding compound specifications match project requirements. Ensure proper handling procedures are followed due to moisture sensitivity classification. Review datasheet revision history for any updates regarding electrical characteristics or package dimensions before finalizing procurement orders.

Selection Notes

Select this regulator when a fixed 1.5V output is required from a 2.5V to 5.5V source. Consider the SOT353 package for space-constrained designs requiring surface mount technology. Evaluate thermal dissipation needs based on input-output voltage differential and load current. Verify that the 150mA output capability meets system peak demand without exceeding junction temperature limits under worst-case ambient conditions.

Part Context

This component belongs to the AP7115 series of low dropout linear regulators designed for portable electronic applications. It serves as a legacy solution within Diodes Incorporated's portfolio, explicitly marked as not recommended for new designs. Engineers are advised to consider the AP7315 series as a modern alternative offering enhanced performance metrics while maintaining similar functional interfaces and application scopes.

Replacement Considerations

Datasheet explicitly recommends using AP7315 as a replacement. Verify pin compatibility and electrical parameter alignment before substitution.
