Overview
The AP7115-30WG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 3.0V output with a maximum current of 150mA. The device operates within an input voltage range of 2.5V to 5.5V and features a typical quiescent current of 50µA. Key electrical parameters include a dropout voltage of 200mV at full load, ±2% output voltage accuracy, and a power supply rejection ratio of 70dB at 1kHz. It incorporates built-in current limit, short circuit protection, and thermal shutdown functions.
Feature Summary
- Integrated shutdown control via the EN pin for power management
- Built-in thermal shutdown and current limit protection circuits
- Low quiescent current suitable for battery-powered applications
- 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 distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status against current regulatory standards. Check datasheet revision history for updates. Ensure ordering suffix matches required package type. Validate supplier credentials before purchase.
Selection Notes
Select this regulator for applications requiring precise 3.0V regulation from varying input sources. Consider the SOT25 package for space-constrained PCB layouts. Evaluate thermal dissipation requirements based on input-output voltage differential and load current. Verify compatibility with external capacitor ESR values for loop stability.
Part Context
This component belongs to the AP7115 series of low dropout linear regulators. It is designed as a cost-effective solution for portable electronics. The specific model indicates a 3.0V fixed output in a SOT25 package with green molding compound. It serves as a legacy alternative to newer series like the AP7315.
Replacement Considerations
Datasheet explicitly recommends using the AP7315 series instead of the AP7115 for new designs. Verify pinout compatibility and electrical specifications when substituting.
