Overview
The AP7115-29WG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a 2.9V 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. It includes built-in current limit, thermal shutdown, and short circuit protection. The component is housed in an SOT-25 package.
Feature Summary
- Integrated shutdown control via the EN pin for power management
- Built-in thermal shutdown and current limit protection circuits
- Low dropout voltage characteristics suitable for battery-powered applications
Applications
- Wireless communication devices
- GSM/GPRS cellular phones
- Handheld mobile devices
- Battery powered devices
- PC and notebook peripherals
Procurement Notes
Verify the specific ordering suffix 'W' confirms the SOT-25 package type as documented. Confirm the 'G' suffix indicates Halogen-free and Antimony-free construction. Ensure compliance with RoHS directives is required for the target market. Check datasheet revision history for any updates to electrical characteristics or recommended operating conditions before finalizing procurement specifications.
Selection Notes
Select this component when a fixed 2.9V rail is required from a 2.5V to 5.5V source. Consider the 150mA output capability against load requirements. Evaluate the 50µA quiescent current impact on system standby power. Verify that the SOT-25 package fits the PCB layout constraints. Note that the datasheet explicitly states this part is not recommended for new designs.
Part Context
This regulator belongs to the AP7115 family of low dropout linear regulators produced by Diodes Incorporated. The series offers various fixed output voltages ranging from 1.0V to 3.5V. The AP7115-29WG-7 specifically denotes the 2.9V version in the SOT-25 package. The manufacturer recommends using the AP7315 for new designs instead of this legacy component.
Replacement Considerations
The datasheet explicitly recommends using the AP7315 as a replacement for new designs. Verify if the AP7315 meets the specific 2.9V output requirement and package compatibility needs.
